title: Using npm to install packages gives command not found?
body: <p>Using npm to install packages, I can never use their cli. For instance, install grunt-cli, avn, nvm, etc. and running </p>
  
  <pre><code>npm install -g avn avn-nvm avn-n    
  avn setup
  </code></pre>
  
  <p>Results in command "avn" not found. I don't know if this is a pathing issue, but my PATH is: </p>
