Check your  npmrc file for a registry entry  which identifies a server acting as a package cache   For me  npm install would hang partway through  and it was because of a old   non-responsive server listed in my  npmrc file  Remove the line or comment it out   gt cat    npmrc  registry http   oldserver 4873   And or check with your IT   project lead as to why it s not working

I m not sure if your problem is being caused by the same reason that mine was  but I too was experiencing a hanging  npm install  and was able to fix it    In my case  I wanted to install typescript locally in the project   npm i typescript --save-dev   For some reason this was conflicting with a global install of typescript that I had  and the shell was just hanging forever instead of finishing or erroring     I fixing it by first removing the globally installed typescript with the -g global flag   npm uninstall typescript -g   After doing this the first command worked

Incase its useful to others  the following is what worked for me   On my machine  although npm proxy was set correctly  npm install waits forever doing something like  sill extract  Re-trying npm install waits forever on the same package again and again    After waiting for a long timeout  npm install printed an error message implying that git was trying to fetch something    The problem vanished after configuring git proxy using the below command   git config --global http proxy https   proxy-server port   Note the https in the value of http proxy without which the configuration did not take effect  Proxy server settings  http   https   port  might vary for users  hence its worth spending a bit of time experimenting with npm and git proxy server settings

I had the same problem  The reason - wrong proxy was configured and because of that npm was unable to download packages   So your best bet is to the see the output of    npm install --verbose   and identify the problem  If you have never configured proxy  then possible causes can be   Very outdated npm version  Some problem with your internet connection  Permissions are not sufficient for npm to modify files
