npm run build in a generated library fails on node-sass dependency

First of all, thanks for making this generator, really helped me understand what format angular wants to use in order to publish a compatible library.

I just wanted to mention that on a freshly generated project I run into this error:

gleb@G1B:~/work/ng2-lib$ npm run build

> ng2-lib@0.1.0 build /home/gleb/work/ng2-lib
> gulp build

fs.js:870
  return binding.readdir(pathModule._makeLong(path), options.encoding);
                 ^

I could solve it by manually running these two commands:

node node_modules/node-sass/scripts/install.js
node node_modules/node-sass/scripts/build.js

Versions:

node: v7.2.1
npm: 3.10.10
yo: 1.8.5
generator-angular2-library: 10.2.2

Running on Debian 8.0 x64

This happens every time I create a new library with generator-angular2-library. Not sure if it’s an issue this generator or node-sass dependency, just wanted to let you know.

Seems to be a common node v6 issue with node-sass. Running this should resolve:

npm rebuild node-sass
