title: Npm on Homestead
body: <p>I just made laravel5 environment using homestead.
  And I did "npm install", and got the errors below.</p>
  
  <pre><code>vagrant@homestead:~/Code/casts$ npm install
  
  &gt; node-sass@3.1.2 install /home/vagrant/Code/casts/node_modules/laravel-elixir/node_modules/gulp-sass/node_modules/node-sass
  &gt; node scripts/install.js

  Binary is fine; exiting.

  <p>I guess "packages.json" could be okay, but the problem might be caused by npm.</p>
  
  <p>Any ideas?</p>
