title: How come npm install doesn't work on git bash
body: <p>I have git bash open and I type in <code>npm install</code> and then it returns:</p>
  
  <pre><code>bash: npm command not found
  </code></pre>
  
  <p>I don't understand, because I have <code>node.js</code> command prompt and when I type in <code>npm -v</code> then it returns <code>3.7.3</code>. How come it doesn't work in git?</p>
