After \"Install

Answer 1

I had the same trouble in getting angular cli to work. I tried almost all the possible solutions listed on stackoverflow and other mediums but got failure.

For me what worked was to run an antivirus security scan on my computer. A malicious program was setting the node_modules inside C://users//AppData/roaming/npm to read only mode. Once that virus got removed, I Installed npm and angular cli again and it finally worked.
