    Bundler, the underlying system Vagrant uses to install plugins,
    reported an error. The error is shown below. These errors are usually
    caused by misconfigured plugin installations or transient network
    issues. The error from Bundler is:
    An error occurred while installing nokogiri (1.6.4.1), and Bundler cannot continue.
    Make sure that `gem install nokogiri -v '1.6.4.1'` succeeds before bundling.
