vue [my-dev●] node
> console.log(require('phantomjs-prebuilt'));
{ path: null,
  version: '2.1.1',
  cleanPath: [Function],
  exec: [Function],
  run: [Function] }
undefined

npm install phantomjs-prebuilt 后:

ue [my-dev●] node
> console.log(require('phantomjs-prebuilt'));
{ path: '/Users/cycold/Developer/github/vue/node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs',
