node.js – When using npm, commands fail due to cache access restriction/lock (errno EBUSY -4082)


I’ve been running into what appears to be a directory access issue in Windows when attempting to use npm. Having tried numerous suggestions from various other SO questions and answers, I thought I’d see if anyone might have suggestions or solutions based on log the output.

I’m continuously running into the error anytime I attempt an npm operation, including install (global or local), uninstall, updateor executing tools such as electron-packager as shown in the package.json scripts section, below the error itself.


  • Operating system: Windows 10 (Build 19043)
  • node version: v18.3.0
  • npm version: 8.12.1

The error output itself is typically :

npm ERR! code EBUSY

Trying to run the scripts results in the same error, with differing details. For example, trying to execute the npm start script. The same is true for npm run build:windowsbut the unfetchable package URL in the error is

❯ npm start

> MyElectronApp@1.0.0 start

Attempted solutions

I’ve tried a number of suggestions from a variety of sources, including (source: npm ERR! code ENOENT npm ERR! syscall rename [StackOverflow]):

  • Clearing the cache with npm cache clean --force then reinstalling (npm install)
  • Verifying the cache with npm cache verify then reinstralling (npm install)
  • Removing node_modules and package-lock.jsonclearing the cache, and reinstalling
  • Removing read-only checkbox from project folder and cache folder (right-click > properties) which seems to immediately get reset

I’ve tried these in dedicated PowerShell terminals (non-admin and admin), and the integrated terminal in Visual Studio Code, all having the same result. I’ve also tried:

  • Repairing the nodejs installation via the installer
  • Uninstalling nodejs and remove node/npm related files and directories, restarting the PC, and reinstalling nodejs and attempting npm install in a fresh PowerShell terminal
  • Rebooting to ensure no other processes are using these directories (such as vscode or another terminal instance)
  • Closing anti-virus program (not attempting a full uninstall) and trying the above solutions

I suspect this relates to permissions on the cache directories, judging by the error message, but since it is npm which creates those directories after the npm cache cleanI’m not sure I understand what more is needed, and am naturally hesitant to change directory permissions (eg NodeJS change file and folder permissions [StackOverflow]) until having received advice.

Thanks in advance!
