title: Installing multiple npm versions
body: <p>Is it possible to install multiple versions of <code>npm</code> for different projects that I am working on or are the <code>npm</code> installations always global? (Windows 10)</p>
  
  <p>Are also tried installing different versions with <a href="https://github.com/marcelklehr/nodist" rel="noreferrer">https://github.com/marcelklehr/nodist</a> but it seems to affect only the node version, not the npm version.</p>
  
  <p>Or does npm version actually matter? Can I just use the newest npm version even when a project says the requirement is a certain npm version?</p>
