error eperm operation not permitted open что делать
Node fs Error: EPERM: operation not permitted, open
I get this error in my app:
Error: EPERM: operation not permitted, open ‘C:\Program Files (x86)\Full Menu\db\main.json’
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?

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.
If you have the file that you can’t open or modify mounted as a volume in docker restarting docker should fix 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.
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
I think that you must change the permissions recursively to the file so the user executing your script can read / write this file.
Restarting my computer fixed this problem for me.
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
If you are facing this issue on Windows 10, then please try the following:
Hope this would of help.
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.
Ошибка узла fs: EPERM: операция не разрешена, открыт
Я получаю эту ошибку в своем приложении:
Ошибка: EPERM: операция не разрешена, откройте ‘C: \ Program Files (x86) \ Full Menu \ db \ main.json’
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?
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.
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.
Если у вас есть файл, который вы не можете открыть или изменить, смонтированный как том в докере, перезапуск докера должен решить проблему.
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:
У меня была ошибка, потому что я уже открывал файл раньше
Перезагрузка компьютера устранила эту проблему.
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:
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.
Итак, чтобы исправить:
After running that command, When trying to run any npm commands on Windows OS I keep getting the below.

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.
Then npm start works in a normal console.
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.
Sometimes, all that’s required is to stop the dev server before installing/updating packages.
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.
And finally was able to run this (installing Angular project) without the errors I was seeing regarding EPERM :
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 could then install the npm package without a problem.
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.
Simplest way
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.
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.
Find this command npm cache clean as a solution to those error in quick and simple way!
A reboot of my laptop and then
Happened to me since the folder/file was locked by another process. Used a tool (LockHunter) to terminate that process and it started working again (possible reason).
I was running create-react-app server. Simply stopped the server and everything worked just fine.
I had the same issue, as I was using my company LAN. And I just ran cmd.exe npm and I was able to execute my other commands without any error after that.
Just sharing this, as it may help other folks who try to do this in their office LAN. Thank you.
I updated my node version to 8.9.4 and ran the necessary install command again from administrator command prompt. It worked for me!
Running the IDE (in my case IntelliJ) in administrator mode and executing npm install does resolves the problem.
If no IDE then run CMD in administrator mode and try executing npm install
Try installing it globally first, using the command
And then, you can create your app using the command,
Install create-react-app
Just stop react server and then install the package.
This issue occurs because when react is running (with yarn start or npm start ), It is using some resources.
The Problem I faced (In Windows Computer)
When I was trying to install a couple of npm packages I got the following error:

Getting «NoPermissions (FileSystemError): Error: EPERM: operation not permitted» when trying to save/create file on Visual Studio Code
I uploaded «mynewfolder» to Visual Studio Code, but when I do «New File» and write «index.html» under that I get this message:
Unable to write file (NoPermissions (FileSystemError): Error: EPERM: operation not permitted, open ‘c:\Users\Projects\MyFirstPage\index.html’)
I tried several times and still get the same error message.
Can anyone tell me what’s going on?

I also meet this problem, now the problem has been solved. Please restart your PC and run your VSCODE as Administrator.
Just Run your VSCODE as Administrator.
check your file permission privilege it should be on read and write.may be the hidden repositories in the folder check and delete it
The solution that worked for me is as follows (this works for Windows OS)
File Explorer will open and Visual Studio Code will be shown
The program will automatically run as Administrator.
If you have encounter any problems, do not hesistate to comment.

It seems like a Windows issue too.
I think too.
chmod/chmodSync occurred to unexpected behavior in Windows.
So, I suggest that we should modify dotf to prevent executing chmodSync when dotf is running on Windows.
grant commented Nov 21, 2018
That looks like a very old issue in Node.

I found description about mode of fs.chmod() on Windows.
@grant
Do you think it is related to this issue?
Caveats: on Windows only the write permission can be changed, and the distinction among the permissions of group, owner or others is not implemented.

@grant
OK. I’ll give it a try!
grant commented Nov 25, 2018
@prprhyt I added dotf@1.2 that includes the patch you wrote.
Can you try updating clasp with this version and see if the Windows issue is fixed?
grant commented Nov 26, 2018
@bv-vd The fix should be applied in the master branch of this repo. If you see it still occurring there, please reopen this issue.
@prprhyt Created PRs to fix this issue.

I had to un-hide the file for it to work. Not sure why clasp run from PowerShell would need the file to be un-hidden?
PopGoesTheWza commented Dec 10, 2019
@imthenachoman Looks like a NodeJS limitation: nodejs/node#14553
Not sure yet how to implement a fix
imthenachoman commented Dec 10, 2019
@PopGoesTheWza Yeah. Very strange issue. I don’t fully understand the technical reason but I assume it has something to do with how Microsoft did something. Oh well. Not a big deal.
PopGoesTheWza commented Dec 10, 2019
I’d adventure a wild guess: Linux and Mac OS have similar POSIX compliant file systems which do not have an hidden attribute. Such attribute I only encounter on Microsoft OSes (DOS and Windows) and a few long since forgotten systems. In order to fully support Windows differences, one would need to either introduce in the NodeJS code base too much specific code, or leave up to apps and package developer to handle it.
