Answer 1

In my case rebooting server and trying again worked.

Answer 2

Updating npm worked for me.

For OSX, Linux - npm install -g npm@latest

For Windows -
Step-1 : Navigate to %ProgramFiles%\nodejs\node_modules\npm and copy the npmrcfile to another folder or the desktop. Then open cmd.exe and run the following commands:

cd %ProgramFiles%\nodejs
npm install npm@latest

Step-2 : Copy the npmrc file back into %ProgramFiles%\nodejs\node_modules\npm.

Answer 3

I found solution here.

Its a network issue. in my previous network there is a proxy setting. i have tried to install it without proxy it worked fine.
