title: node-sass@4.5.1 postinstall: `node scripts/build.js`
body: <p>I am trying to build angular-cli on jenkins and getting below error. I am using node (v6.10.0) and npm( v3.10.10). I don't have any direct dependency for node-sass in my package.json so it looks like a peer dependency. I have google this error and it looks like there is some issue with node/npm version. I am using latest version of node so really not sure what's the issue here.</p>
  
  <p>node-sass@4.5.1 postinstall: <code>node scripts/build.js</code></p>
