Going to switch the test to use json instead of sass for now (https://rubygems.org/gems/json). I think it should work with CentOS 7.

Ha, now:

    TASK [geerlingguy.ruby : Install Bundler.] *************************************
    fatal: [instance]: FAILED! => {"changed": false, "cmd": "/bin/gem install --no-user-install --no-document bundler", "msg": "ERROR:  Error installing bundler:\n\tbundler requires Ruby version >= 2.3.0.", "rc": 1, "stderr": "ERROR:  Error installing bundler:\n\tbundler requires Ruby version >= 2.3.0.\n", "stderr_lines": ["ERROR:  Error installing bundler:", "\tbundler requires Ruby version >= 2.3.0."], "stdout": "", "stdout_lines": []}

So I'll disable bundler install on CentOS 7 for now.
