I have searched for solution and found out that running the below commands:

npm cache clean --force
npm cache verify

should solve the issue, but the issue still exits after running these commands and clearing cache.

My npm version is 6.4.1 and node version is v10.15.3

Answer 1

This issue was solved by going to C:\Users\USERNAME\AppData\Roaming\npm-cache and deleting its contents manually and then later running cmd as Administrator and running npm install

NOTE: Running cmd as Administrator was to solve another error that occurred after deleting cache manually and running. The new issue was npm WARN tarball tarball data for [email protected] seems to be corrupted. which would freeze the installation at this point. On searching the internet, found out that it might be due to lack of permission, as it was since it was solved after running as Administrator.
