On Windows 7 for node 5.5.0 if ".node_repl_history" has hidden attribute, node fails to open.
The text was updated successfully, but these errors were encountered:
mrnerdhair commented Mar 13, 2016
As a workaround, you can put .node_repl_history in a folder, set the folder hidden, create a symlink (with mklink ) called .node_repl_history to the real file in the hidden folder, and then use attrib /l +h to set the hidden attribute on the symlink but not the file itself. This is stupid, but at least it declutters my user folder.

Maybe we should just continue if there is an error and warn in the repl?
mrnerdhair commented Mar 14, 2016
The problem is that the error should not occur. Just because the file is set hidden should not cause a permissions error.
thefourtheye commented Mar 14, 2016
@t0lkman Few of us don't use. So can you please show the actual error stack trace or explain in detail what exactly happens?
Edit: nvm. I see the title now.

I think printing a warning is the best bet. If the user has been fiddling with the file, maybe they don't want Node writing to it. Or, maybe they hadn't realized, and printing a warning will help them fix it.
t0lkman commented Mar 14, 2016
@cjihrig I don't agree with you, I always hide all unnecessary system files on Windows, hidden files shouldn't be considered "read only" hence I don't need any warnings
mrnerdhair commented Mar 15, 2016
The file is supposed to be hidden. On POSIX systems, the file name starting
with a dot is the marker for a hidden file, so it should be hidden by
default. If a user didn't want it to be writable, they would have set the
read-only bit--which is right next to the checkbox for the hidden bit.

The app I have is built with electron-boilerplate. I am using this function to get the path to the root of the app:
And this is the script that writes the file:
I know what the problem is: permissions. But how could I get this working without running the app as an administrator?
I have the same issue in my window 11. I have deleted the same file and then laravel recreate the same and it works.

For the benefit of searchers; I has this error. I added full permissions for Everyone as a test, but that didn't fix it. The issue was that the file was set to readonly (by source control).
Unchecking the readonly option in the file properties fixed the issue.
This is the current fix that I am having to do at the moment. TFS + VS2015 marks the file as readonly when you check anything in and this breaks my gulp build script. Marking the files as not being readonly solves the issue, though it does make VS complain a lot about the files saying that there is an Existing or non-version controlled version of the file . Be careful with this as you may lose changes or even files when getting latest version.
Also had this issue, required to use Perforce (pray for me) and it regularly sets to read only when syncing files. Right Click > Untick Read Only fixed the issue.
On my Windows 10 machine, I encountered this error when running an old Node JS project. I think Node version 10.16.
In any case, it was trying to modify a dotfile in my project. Be sure that the file isn't hidden on Windows. After unchecking the hidden option in the file properties pop up. Everything worked.
- Right click file in Windows Explorer
- Select properties
- Uncheck Hidden
- Click Ok
- Re-run your command.
If you have the file that you can't open or modify mounted as a volume in docker restarting docker should fix the issue.
i had to run the node command prompt as administrator and that fixed the issue.
I face this issue when I was deleting a file/folder.
Solution:
Just restart your code editor/ terminal Or Restart your computer
If you are facing this issue on Windows 10, then please try the following:
- Uncheck readonly options for the folder (if read-only reverts, login as administrator)
- Open terminal as administrator (if you are facing this issue on terminal)
- Switch off ransomware folder protection
- Change chmod of the folder
- Check if the folder is hidden or not
- Disable antivirus protection (temporarily) and try this
- Or move your project folder somewhere else, where antivirus ransomware protection is disable.
Hope this would of help.
I think that you must change the permissions recursively to the file so the user executing your script can read / write this file.
I solved the problem by changing the NSIS script so it will allow me to choose another installation folder.
Restarting my computer fixed this problem for me.
I had this issue too. I'm using TFS (or VSO, Azure DevOps, etc.) for source control. I was trying to compile from .scss to .css and it couldn't open my .css. I just needed to right-click on my .css file and Check Out for Edit.
I had the error because i have already open the file before
this is not an exact answer but may help:
i think if you want to read or readSync a file that doesn't exist you will encounter an EPERM error.
in many programming languages, any permission related error may not directly means an actual permission issue
for example in PHP Folders (not files) must delete by php rmdir() method but if you want to do that with unlink() , u will encountered with a wrong Warning message that says "permission denied"
I had the same problem, when i tried to create and write to a file using NodeJS. I thought it had to do with my windows file/folder access permissions, but after restarting my computer and running the code again, I still got the same error.
However, this time around my antivirus gave me a pop-up message also, stating that it blocked permission for Node.exe to write or open files. So once I flagged Node.exe as safe for my anti-virus program (Avast).
It worked for me. Disabling my antivirus could've also temporarily fixed it, I guess.
After running that command, When trying to run any npm commands on Windows OS I keep getting the below.
Have deleted all files from
It did not work.
Did you run it in the cmd.exe "terminal" (command prompt) or from the GitBash terminal? For me, it failed when I ran it in GitBash but worked fine when I ran it in cmd .
Today I got EPERM even in cmd.exe . But I ran the following command standing in C:\Program Files\nodejs , and it seems to have worked: npm cache clean --force && npm install

Running this command was my mistake.
npm config set prefix /usr/local
Path /usr/local is not for windows. This command changed the prefix variable at 'C:\Program Files (x86)\Git\local'
To access and make a change to this directory I need to run my cmd as administrator.
- Run cmd as administrator
- Run npm config edit (You will get notepad editor)
- Change prefix variable to C:\Users\\AppData\Roaming\npm
Then npm start works in a normal console.
In my case, I simply uncommented prefix (was ;prefix. ) after npm config edit , and Profit. Not sure if that's A Smart Thing, but it worked.
This is occurring because windows is not giving permission to the user to create a folder inside system drive. To solve this:
The Folder > Properties > Security Tab
Click on Edit to change Permissions > Select the user and give Full Control to that user.
Granting the user access to change system folders is not a good idea, especially when this can be easily fixed by changing the prefix to a folder in the user's home directory.
In our case we have full control but folder was hidden. If you have already full control then check hidden option of the folder.
This answer worked for me, I gave the Full Control permissions to Users from the Security tab of the folder properties
Sometimes, all that's required is to stop the dev server before installing/updating packages.
how odd but true. installing react-dom@16.7.0-alpha.0 for trying out react hooks didn't work until trying this
To add to this, if you suspect this issue is your dev server running but don't know how to stop it, just logout / restart your windows will always fix this lool
I solved the problem by changing windows user access for the project folder:
I recently had the same problem when I upgraded to the new version, the only solution was to do the downgraded
Install the previous version:
Try update the version in another moment.
Restarting VsCode solved it for me!
I use Windows 10. I started the CMD as administrator, and it solved the problem.
Find CMD, right click, and click open as administrator.
@EtienneGautier That's. simply not true at all. What's your proposed solution for modifying system files? If there's any way to do it other than with "administrator permissions" then there's something seriously wrong with the OS's security.
Hey @Clonkex, I was assuming that the context was NPM's one (according to the question). Still my comment is not relevant, I'm deleting it. Thank you for your feedback.
I had an outdated version of npm . I ran a series of commands to resolve this issue:
Then (once again):
And finally was able to run this (installing Angular project) without the errors I was seeing regarding EPERM :
As of npm@5 it is recommended if you use npm cache verify AKA a self healing mechanism ; which will ensure everything is consistent
In my case, I was facing this error because my directory and its file were opened in my editor (VS code) while I was running npm install . I solved the issue by closing my editor and running npm install through the command line.
I had the same problem, after updating npm. Solved it by re-installing latest npm again with:
but this time with cmd running in administrating mode.
i did all this because i suspected there was an issue with the update, mostly some missing files.
I had the same problem when I tried to install the npm package AVA . The solution for me was to delete the node_modules folder and force-clean the npm cache:
I could then install the npm package without a problem.
Yes, I somehow was having node_modules folders in the current working directory. It was throwing that exception when I tried to run angular cli commands 'ng new..'. Deleting node_modules folders helped.
for me it was an issue of altering existing folders in node_module, so i nuked the whole folder and run npm install again. it works with no errors after that
Just run cmd as admin. delete old node_modules folder and run npm install again.
npm install should work without starting CMD as admin. It is not working on normal cmd(non admin) is also an issue.
Hope I am not too late for this post but recently even I too got hit by this issue. And also I had no admin rights on my laptop.
Here is the simplest way I fixed the bug.
- Locate the file name .npmrc (it will be in C:\Users\\.npmrc )
- Open it and change the path of prefix= to prefix=C:\Users\\AppData\Roaming\npm
hope it will be helpful..
If you getting this error in an IDE's terminal/commands prompt, try delete node_modules, close IDE, and run the npm install command again. The time when IDE started but still not completed its analysis of node_modules tree is a tricky moment, when packages installation may fail because IDE still scanning node_modules contents.
This error is caused by different problems try the below one of them will work for you!
try to run npm as Administrator
Run cmd as administrator npm config edit (You will get notepad editor) Change Prefix variable to C:\Users\\AppData\Roaming\npm
The errors went after I disabled my anti-virus (Avast)
Sometimes a simple cache clear like the below would fix it.
When I was trying to install a couple of npm packages I got the following error:
npm - EPERM: operation not permitted - while npm was trying to rename a file
Here's my debug snippet for reference, if you've faced the similar problem:
After carefully checking out the answers from other users, I have created a detailed answer for the community
My Solution for the problem
Follow the mentioned steps
- Right-click on the project folder
- Go to properties -> Security Tab
- Select Users -> Edit
- In the Permission for Users section, Full control -> Give a check mark in Allow -> OK
- Wait for Windows security to apply the new security rules
- Click OK
Visualization of the steps
If you follow these steps and try to install npm packages again it will work properly.
Note: It's a best practice to close and open up the command line again to experience the changes
Приложение, которое у меня есть, построено на электронном шаблоне. Я использую эту функцию, чтобы получить путь к корню приложения:
И это сценарий, который записывает файл:
Я знаю, в чем проблема: разрешения. Но как я могу заставить это работать, не запуская приложение от имени администратора?
- Предоставление полных разрешений директории, в которую он должен записать файл.
- Как это сделать на машине с windows
В интересах поисковиков; У меня такая ошибка. Я добавил полные разрешения для в качестве теста, но это не помогло. Проблема заключалась в том, что файл был установлен на (системой управления версиями).
Снятие отметки с опции в свойствах файла устранило проблему.
- 1 Это текущее исправление, которое мне нужно сделать в данный момент. TFS + VS2015 помечает файл как , когда вы что-либо проверяете, и это нарушает мой сценарий сборки gulp. Пометка файлов как непрочитанных решает проблему, хотя это заставляет VS много жаловаться на файлы, в которых говорится, что существует . Будьте осторожны с этим, так как вы можете потерять изменения или даже файлы при получении последней версии.
- Также была эта проблема, необходимая для использования Perforce (молитесь за меня), и она регулярно устанавливается только для чтения при синхронизации файлов. Щелкните правой кнопкой мыши> Снять отметку Только для чтения, устранена проблема.
Мне пришлось запустить командную строку узла от имени администратора, и это устранило проблему.
Я думаю, что вы должны рекурсивно изменить права доступа к файлу, чтобы пользователь, выполняющий ваш скрипт, мог читать / записывать этот файл.
- Я решил проблему, изменив сценарий NSIS, чтобы я мог выбрать другую папку для установки.
Если у вас есть файл, который вы не можете открыть или изменить, смонтированный как том в докере, перезапуск докера должен решить проблему.
- 1 Этот ответ, похороненный среди тысяч страниц, которые я просматривал, буквально спас меня. Я терял рассудок. По какой-то причине мой глоток не удалял мою карту css, и часто перезагрузка ПК исправляла это, но на этот раз это не помогло. Я все перепробовал, и перезапуск Докера сработал. Не знаю, как и почему, но черт возьми!
Если вы используете Windows 10, необходимо отключить защиту от программ-вымогателей. Защита от программ-вымогателей предотвратит любые изменения папок и файлов. Вы можете отключить ее в Центре безопасности Windows. Смотрите скриншот ниже:
- Даже если это решит проблему, это будет рискованно. Не облегчайте злоумышленникам возможность вымогательства вашей системы. Найдите другой способ.
У меня была ошибка, потому что я уже открывал файл раньше
Перезагрузка компьютера устранила эту проблему.
У меня тоже была эта проблема. Я использую TFS (или VSO, Azure DevOps и т. Д.) Для управления версиями. Я пытался скомпилировать из .scss в .css, но не смог открыть мой .css. Мне просто нужно было щелкнуть правой кнопкой мыши мой файл .css и проверить его на редактирование .
Я сталкиваюсь с этой проблемой, когда удаляю файл / папку.
Решение:
Просто перезапустите редактор кода / терминал или перезагрузите компьютер.
это не точный ответ, но может помочь:
я думаю если вы хотите или файл, который не существует, вы столкнетесь с ошибкой .
во многих языках программирования любая ошибка, связанная с разрешениями, может не означать напрямую фактическую проблему с разрешениями.
На моем компьютере с Windows 10 я столкнулся с этой ошибкой при запуске старого проекта Node JS. Думаю, Node версии 10.16.
В любом случае, он пытался изменить точечный файл в моем проекте. Убедитесь, что файл не скрыт в Windows. После снятия отметки со скрытой опции в свойствах файла всплывают. Все заработало.
I'm building an import procedure which does a large number of requests inside of a single Promise.all , and storage.get is being used inside of electron's session.webRequest.onBeforeSendHeaders (as an authentication mechanism)
I think this has to do with the concurrency in the event loop. There's a lot of calls on storage.get that stack up before getting resolved.
Only solution I can think of is that I implement a lazy cache somewhere, which I will probably end up doing. But I was wondering if this is a known limitation/issue of electron-json-storage .

Hi, @jviotti my app is installed on more than 1k Windows and 400 Mac computers and 5-10% Windows users are facing the same issue. Everything is fine on the Mac.
I have noticed this error from last 3 weeks, earlier I was also thinking it only comes when locking unlocking the system. But it is not true. It comes anytime, and when the user tried to click ok it comes again continuously many times.
jviotti commented Sep 10, 2018
@valhalla13 @SirWaddles Do you mean it comes on any fs function call? Does it also happens when locking and unlocking? Does it eventually succeed if you keep trying? Can you check if people that see this error have any anti virus installed? I remember seeing something similar with various anti virus which would request exclusive access to files while scanning them, and thus causing EPERM for anyone else trying to access them.
It'd really help if you can share a stack trace with me.
SirWaddles commented Sep 18, 2018 •
@jviotti Hi, sorry about taking this long.
I don't think this is the trace you're after, but it seems to be the only one I'm able to print.
I don't have any anti-virus, apart from Microsoft Defender and this is happening in my environment.

zankooh commented Oct 5, 2018 •
I have the same exact problem with v4.1.3.
This might not be the problem, but I have noticed that the error occurs whenever I call storage.get(key) with different keys in the same script.
For example:
storage.get('item', function() <>)
storage.get('anotherItem', function() <>)
Now, I am not using these methods directly. I have made service wrappers and call functions which return promises that resolve the data returned from the storage.get() method. Even in this case, when I chain the promises (This is some badly written code. It is just an example.):
jviotti commented Oct 7, 2018
Hm, that's very interesting. Do you have a stack trace you can share?
ozooner commented Nov 15, 2018
I upgraded our app to 4.1.4 from 4.1.3 in hopes to get the bug fixed, but I can confirm that 4.1.4 still has the issue. I myself am unable to reproduce it, but it happens on about 5-10% of our windows users. There are very few OSX and Linux installs, so I can't rule them out completely, but no incidents there so far.
No stack to share unfortunately, as I can't reproduce it on my machine, but I can agree that it seems to happen when reading the file multiple times
zankooh commented Nov 26, 2018
I think I managed to solve the problem. It might not the electron-json-storage itself. The problem might be file system related.
Whenever I read a .json file with electron-json-storage, the file gets temporarily locked (by the file system I assume?) and then it gets unlocked, being free to read without any problems. Now, if I try to read the same file while it's locked, I get the error. In order to avoid the problem, I store the data with electron-json-storage (for permanent storage) and localStorage at the same time, but read data from localStorage only. In case localStorage gets cleared, I read all data stored with electron-json-storage and write it to localStorage.
I haven't had the problem since.
ozooner commented Nov 26, 2018
jviotti commented Dec 2, 2018
Very interesting! Presumably this is a Windows only issue, right? I think we could add logic to electron-json-storage to retry if it gets an EPERM during reads for this reason. I sadly only have access to a Windows VM nowadays, and I can't seem to be able to reproduce on that setup.
