title: Error installing node-sass dependency
body: <p>I am trying to npm install a package.json with the following dependencies:</p>
  
  <pre><code>  "devDependencies": {
      "browser-sync": "^2.8.2",
      "del": "^1.2.0",
      "gulp": "^3.9.0",
      "gulp-autoprefixer": "^2.3.1",
      "gulp-babel": "^5.2.0",
      "gulp-concat": "^2.6.0",
      "gulp-eslint": "^1.0.0",
      "gulp-filesize": "0.0.6",
      "gulp-header": "^1.2.2",
      "gulp-imagemin": "^2.3.0",
      "gulp-jshint": "^1.11.2",
      "gulp-livereload": "^3.8.0",
      "gulp-minify-css": "^1.2.0",
      "gulp-newer": "^0.5.1",
      "gulp-notify": "^2.2.0",
      "gulp-plumber": "^1.0.1",
      "gulp-rename": "^1.2.2",
      "gulp-sass": "^2.0.4",
      "gulp-sourcemaps": "^1.5.2",
      "gulp-svgmin": "^1.2.0",
      "gulp-svgstore": "^5.0.4",
      "gulp-uglify": "^1.2.0",
      "imagemin-pngquant": "^4.1.2"
    },
    "dependencies": {
      "node-sass": "^3.2.0"
    }
  </code></pre>
  
  <p>But it fails with the node-sass package. 
  A part of the output is this:</p>
  
  <pre><code>Cannot download "https://github.com/sass/node-sass/releases/download/v3.2.0/darwin-x64-51_binding.node": HTTP error 404 Not Found
  </code></pre>
  
  <p>And then:</p>
  
  <pre><code>node-sass@3.2.0 postinstall: `node scripts/build.js`
  npm ERR! Exit status 1
  npm ERR! 
  npm ERR! Failed at the node-sass@3.2.0 postinstall script 'node scripts/build.js'.
  npm ERR! Make sure you have the latest version of node.js and npm installed.
  npm ERR! If you do, this is most likely a problem with the node-sass package,
  npm ERR! not with npm itself.
  npm ERR! Tell the author that this fails on your system:
  npm ERR!     node scripts/build.js
  npm ERR! You can get information on how to open an issue for this project with:
  npm ERR!     npm bugs node-sass
  npm ERR! Or if that isn't available, you can get their info via:
  npm ERR!     npm owner ls node-sass
  npm ERR! There is likely additional logging output above.
  </code></pre>
  
  <p>Node version 7.5.0 and npm version 4.1.2, OSX Sierra</p>
  
  <p>Any suggestions?</p>
