'npm cache clean' not working angular VS Code as IDE

Question

npm ERR! As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead. npm ERR! npm ERR! If you're sure you want to delete the entire cache, rerun this command with --force.

npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\janak\AppData\Roaming\npm-cache_logs\2017-08-11T04_38_31_995Z-debug.log

Answer 1

Run the command with --force:

npm cache clean --force

Based on npm documentation:

it should never be necessary to clear the cache for any reason other than reclaiming disk space, thus why clean now requires --force to run.

Answer 2

Try deleting your node_modules folder inside your project, and then run npm install again.
