npm not working after clearing cache

Before clearing cache

npm cache clear

npm is working fine. After clearing cache, it is not working. The error log below suggest problem with internet connectivity but internet connection is just fine. This problem does not only happen for bower but for any modules.

Here's the output of process:

Try npm cache clean --force if it doesn't work then manually delete %appdata%\npm-cache folder.

I solved this issue by running cmd as an administrator. before that, I was trying to run in vs code.

run it in Power Shell or Cmd with administrative privilege. I hope that it will help.

npm install –g @angular/cli@latest

I try to

npm cache clean

But npm said newer version on npm (> 5) has self healing Mechanism and every thing i need to do for checking npm is use verify

npm cache verify

npm message :

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.

but for forcing npm use this:

npm cache clean --force
