npm - Error: EPERM: operation not permitted, unlink 'D:Sources** ode_modulesfsevents ode_modulesabbrevpackage.json'

Question

I just updated npm to 5.4.0.
Now, Whenever I want install a npm package I get the following error:

D:SourcesDownloadCmsMd.DownloadWeb.Angular>npm install mds.angular.datetimepicker@latest --save
npm ERR! path D:SourcesDownloadCmsMd.DownloadWeb.Angular

I'm dead sure, run CMD as administrator.

Also I checked D:SourcesDownloadCmsMd.DownloadWeb.Angular ode_modulesfsevents ode_modulesabbrevpackage.json, package.json is not exist in path !

Edit: Upgrade to v5.4.1, still get the same error, even cannot work around with --no-optional :-(

Answer 1

I was able to fix this by running the command prompt/bash as admin and closing VSCode! Seems like VSCode was locking some files. Potentially something else could be locking these files for you.
