title: npm install: node-waf not found. What to do?
body: <p>Using node -v v0.10.29, npm -v 1.4.14 (<a href="http://ppa.launchpad.net/chris-lea/node.js/ubuntu" rel="noreferrer">http://ppa.launchpad.net/chris-lea/node.js/ubuntu</a>)</p>
  
  <p>when doing a "npm install" of a project, "zlib@1.0.5 preinstall" always shouts "sh: 1: node-waf: not found"</p>
  
  <p>I've seen some other questions about the same thing, but I still don't know what I have to do to make "npm install" work.</p>
  
  <p>Thanks.</p>
