npm ERR! EPERM : operation not permitted , scandir

Question

Our deployment process uses Jenkins, but sometimes our build fails with the following

We are using npm version : 6.7.0. Any help would be greatly appreciated!

Answer 1

I think the issue is another process is utilizing that folder so it's locked down, perhaps from a previous build. I would try the following to resolve your issue:

1. Try running as an admin for your build and see if that resolves the permission error.
2. Clear out your npm cache prior to installing: npm cache clean --force
3. Look into yarn for dependency management.

Hopefully that helps!
