title: Angular 2 issue: typings: command not found
body: <p>So this might come off as a really basic question but it has been bugging me for days now and haven't actually found a solution.</p>
  
  <p>I'm installing typings from the command line with npm and it appears to run well but then I type any typing command and it says that the command doesn't exist!</p>
  
  <p>It goes something like:</p>
  
  <pre><code>    Kevyns-MacBook-Pro:~ kevynquiros$ sudo npm install typings --global

  </code></pre>
  
  <p>And then this is what happens:</p>
  
  <pre><code>Kevyns-MacBook-Pro:~ kevynquiros$ typings search tape
  -bash: typings: command not found
  </code></pre>
  
  <p>Please help!</p>
