In my situation this helped  Before proceeding to execute these commands close all VS Code instances   clean cache with  npm cache clean --force   install the latest version of npm globally as admin   npm install -g npm latest --force   clean cache with  npm cache clean --force   Try to install your component once again    I hope this works for others  if not you may also try temporarily disabling antivirus software before trying again

I face this issue multiple times   It turns out  that it has nothing to do with permissions  cache  etc  The error message is misleading  For node v 6 x you will see more detailed error stack but not after 7 x For me and my colleges  the issue is timeout function  Basically the package install has not finished yet  i e  holding the directory  when npm tries to delete it  in node 6 x you can see that in finalize js now it s gone   Just use yarn

npm was failing for me at scandir for   npm install -g webpack      which might be caused by npm attempting to  modify  files that were potentially locked by other processes as mentioned here and in few other github threads  After force cleaning the cache  verifying cache  running as admin  disabling the AV  etc the solution that actually worked for me was closing any thing that might be placing a lock the files  i e  restarting my computer      I hope this helps someone struggling

I had the same problem  The reason for the error is unsupported characters in the path to the file  Replaced the cyrillic in English - it helped

User · Answer

This might be due to your Antivirus software  If you can not disable AV then you can try modifying your NPM global install location as node installs into APPDATA directory which is actively monitored by AV Engines  Try running following commands-  npm config set prefix  YOUR CUSTOM LOCATION  npm config set cache  YOUR CUSTOM LOCATION   Delete node modules directory and install your package again

If you want to avoid the --force option  which is always a better approach   I suggest making sure that you have stopped running the project  as this is usually the main reason for locking the files in almost 90  of the cases I have seen  I suggest the following steps in this order   1- In Angular stopping ng s and in React stopping  npm start usually solves this issue because usually this error happens if a development server is running the project as it locks some files  amp  then npm can t update them thus throwing this error  2- If the above doesn t work  then try closing the code editor that has the workspace opened in it  maybe it was locking some files or something   So try closing the code editor  amp  running   npm install   3- If still it doesn t work  then maybe you can try the --force option  npm install --force
