I agree the original approach was not the best. The requirement of 
providing source was met by build depending on node-autoprefixer and 
generating this file during ruby-autoprefixer-rails build (this meant 
there was extra effort required to rebuild when node-autoprefixer 
changes). But I agree, it is better to build this in node-autoprefixer 
itself, even though upstream does distribute the built file in 
autoprefixer node module.

But node-autoprefixer is not building any more (even the original 
build), it fails with this error.

$ sbuild

I noticed node-fs-extra is using /usr/lib/nodejs

$ apt-file list node-fs-extra
node-fs-extra: /usr/lib/nodejs/fs-extra/lib/__tests__/promise.test.js
[...]

Shouldn't this be fixed in node-fs-extra?
