Question

I've installed node.js and git hub. I've modified environment variable too. When I go to folder where package.jason file is present and type following command

  npm install

I'm getting untar error. Here is detailed error

I was executing this command in wrong directory . Before npm install we need to execute

export PATH=$PATH:directory-to-add

Then run

npm install
