Had the following error being thrown when trying to install the
$ vagrant plugin install vagrant-vbguest Installing the 'vagrant-vbguest' plugin. This can take a few minutes... 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 ffi (1.9.5), and Bundler cannot continue. Make sure that `gem install ffi -v '1.9.5'` succeeds before bundling. Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /Applications/Vagrant/embedded/bin/ruby extconf.rb checking for ffi.h... *** extconf.rb failed ***
Followed the trail of suspects, including the above note to install the 'ffi' gem, and noticed that:
