Hey @tusharkant15 ,
It seems there's some problem with connection to npm on your side that causes the trouble. You can try executing manually the command that fails in CLI's code:

npm view tns-core-modules versions --json

And see what's the output.

In case you are working behind a proxy, you can set the required configuration to npm. More information is available here

As the issue does not seem related to NativeScript CLI itself, I'm closing it, but feel free to reopen it in case you have some concerns.
