can not install vagrant-vbguest

Question

I am unable to install vagrant-vbguest on OS X 10.10.4, because it says it can't install Nokogiri.

I have:

• ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]
• Vagrant 1.6.2
• VirtualBox 4.3.12

The maddening thing is that I do have nokogiri installed already:

> whereis nokogiri
/usr/bin/nokogiri

> /usr/bin/nokogiri -v
# Nokogiri (1.6.6.2)

And I can reinstall it individually:

And yet:

It does look like the problem has nothing to do with nokogiri, but I was not able to find a solution.

Any ideas?

Well, you never issued the command mentioned in the error message. Is ruby 2.0 your system install of ruby? If so, why oh why are you messing around with it? If not, you should not be installing gems with sudo. – Gynecic

If you are referring to gem install nokogiri -v '1.6.6.2', just scroll up a bit and you'll see that I did, and it succeeded. I'm not sure what you mean by "messing around with it". I did list my version of Ruby at the top. I tried sudo after failing without sudo, just to see whether that might make a difference. I'm not a ruby developer, so I'm just following a trial and error process of elimination, not really understanding what's going on. That's why I'm posting here, after all. – Implead

This question is quite old, but searchable. Vagrant is pluggable, and I expect it embeds Ruby, instead of working with the system Ruby you might use for scripting.

You shouldn't have to worry about Ruby gems anyway because you can install plugins right from your Vagrantfile:

# Install required plugins

  required_plugins = %w( vagrant-vbguest )

  plugin_installed = false

  required_plugins.each do |plugin|

    unless Vagrant.has_plugin?(plugin)

      system "vagrant plugin install #{plugin}"

      plugin_installed = true

    end

  end
