An unexpected error occurred: "EPERM: operation not permitted in Yarn

I am having problems installing new npm packages with Yarn. Every time I go on to add a new package it's throwing me this error. But when I delete my node_modules folder and run Yarn, everything works fine. Again when I try to add another package, it throws me the same error. Any solutions, I am having a headache right now.

For me, I was running 2 yarn installs simultaneously on 2 different projects on my machine and that caused the issue. I had to do the installs one after the other.

I have this problem all the time with IntelliJ IDEA.

It seems Node Processes keep running in the background and block the installation.

Some of the candidates are

@esbuild
@swc
@nx

Maybe some are intended to run in the background, but I wish yarn could kill them at least on installation.

As a solution, I go to the Task Manager and kill all node processes within the IntelliJ IDEA group on Windows

I had this exact bug happening. I had to stop Visual Studio Code, then I re-ran the command and it just worked.

Seems like the dev server in Visual Studio was locking a file.

I had the same issue, which was solved with this Python script

import os

# Find all Node.js processes
pids = os.popen('tasklist /v /fi "imagename eq node.exe" /fo csv').read().strip().split('\n')[1:]
pids = [int(pid.split(',')[1].replace('"', '')) for pid in pids]

# Kill all Node.js processes
for pid in pids:
    os.system(f'taskkill /pid {pid} /f')

Now the error [Error: EPERM: operation not permitted is gone

If you are trying to install a package, include the force flag --force.

If faced the above error while trying to install the heroicons package.

$ npm install @heroicons/react --force

By including the force flag npm was able to force the installation.

Note: Before attempting installation, stop the development server.

Hope you find this helpful.

For me the issue was that yarn.lock file was set to readonly by Perforce, as I pulled it from a Perforce repository.

Stop the all-running server(project) using ctrl + C.
Then run yarn

In my case, this was because Virtualbox client host-shared filesystem default didn't allow symlink.

The solution is to allow symlink feature for the filesystem which is shared between virtualbox client and host by:

$ VBoxManage setextradata <client-name> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<shared-fs-name> 1

at the host. Where, <client-name> is the vbox client name, and <shared-fs-name> is the shared folder(or filesystem) name between host and client.

See https://www.virtualbox.org/ticket/15945

It seems that VScode block something by its internal process, it might be an extension like language service, or jest process, so if you want to get rid of affecting by VScode internal processes - you can just use external terminal, or open vscode new window and put bash to editor area. It works for me.

If you are still facing the problem and you are using VS Code, try this way

Close your VS Code
Back to home
Right click on VS Code icon
Click on 'Run as administrator' and allow permission
Then navigate to your project directory and try again

Option No - 1: You can install that package with "npm" instead of "yarn"

Option No - 2: press "Ctrl + C" to stop running server and then install again.

What worked for me is stopping the development server, closing VS Code, deleting node_modules and running the yarn command with administrator rights.

Sometimes when this occurs, you may first try to uncheck node_modules folder to read only. If it is not working try to stop the running server and install your packages and then restart the server.

if you're using visual studio code, cmd, or Windows Terminal, close it and run it in administrator mode. Usually, the reason for that error message is a result of limited privilege giving to the editor or npm or Yarn if you're using that.
