My npm is getting stuck a lot, whether its npm install from package.json or individual packages.

Right now, I\'m not even able to sudo npm install

Answer 1

There are a lot of different things that can cause this issue.

I had tried a lot of things, including most of the answers posted here, but no luck.

For some weird reason, this was my ISP's issue. It worked fine when I tried on a different ISP.
