Desired functionality.

Mention any other details that might be useful.

It gets stuck at this message for long times and while this time, CPU usage reaches up to 95+%. Note that i installed Angular CLI and it worked just fine. This scenario is also encountered on a hit or miss basis on some repositories. Sometimes it occurs, sometimes not. I cant really make out the cause. I tried running it in PowerShell with administrator, uninstalling and reinstalling nodejs (both 64bit and 32bit versions) and clearing/verifying npm cache. Still the same problem.

For e.g. try with this repo https://github.com/cornflourblue/mean-angular2-registration-login-example

npm install failing is not a bug of the CLI, I would suggest looking into npm installation issues on stackoverflow or consulting npm documentation. Good luck!
