title: Npm package installation fails - how to restore the old working version?
body: <p>It seems that failed installations attempts with <code>npm</code> delete old versions without installing new ones, which is very frustrating.</p>
  
  <p>Can I go back to the old package version that worked?</p>
  
  <p>I get this error:</p>
  
  <pre><code>gulp
  -bash: /usr/local/bin/gulp: No such file or directory
  </code></pre>
  
  <p>But I can see I still have old versions of Gulp installed. Any way I can make the accessible via command line (put it manually in <code>/user/local/bin</code> ?) them until the issue with new version is fixed?</p>
  
  <p>Can't do anything now with gulp!</p>
  
  <p>Thanks!</p>
