PhantomJS Error: 'QXcbConnection: Could not connect to display'

[1000miles]

When trying to run the specs we get a lot of errors due to phantomjs.

Example (corrected)

69.2) Failure/Error:

If we try to check the version or where phantomjs is located, we get following error:

ubuntu@ubuntu-xenial:/vagrant$ phantomjs --version
QXcbConnection: Could not connect to display
PhantomJS has crashed. Please read the bug reporting guide at
<http://phantomjs.org/bug-reporting.html> and file a bug report.
Aborted (core dumped)

Re-installing phantomjs and phantomjs-prebuilt as mentioned in our README.md it causes a lot of errors as well, e.g.

ubuntu@ubuntu-xenial:/vagrant$ sudo npm install -g phantomjs-prebuilt
/usr/local/bin/phantomjs -> /usr/local/lib/node_modules/phantomjs-prebuilt/bin/phantomjs

> phantomjs-prebuilt@2.1.14 install /usr/local/lib/node_modules/phantomjs-prebuilt
> node install.js

Considering PhantomJS found at /usr/local/bin/phantomjs
Looks like an `npm install -g`

The phantomjs issue happened to @justahero and me. We fixed this by following these instructions.

We might need to update the README.md at a later time, wanted to document it first.
