title: How to find what node version a project supports
body: <p>Is there a way besides trial and error to detect what node version I should use on a repository ?</p>
  
  <p>With the fast rise of web frameworks it's becoming a common need to go back to projects from 6, 12 or 24+ months ago. 
  I've been doing this a lot in the last weeks and my process for detecting the correct node version has become:</p>
  
  <pre><code>git clone [REPO]
  npm i
  [build]
  ### if error
  rm -r node_modules
  nvm use 4, 5 or 6
  npm i
  [build]
  </code></pre>
  
  <p>I can't help but feel that there's something very basic I'm missing here.
  Thanks for any wisdom you can share with me!</p>
