how to detect from a Vagrantfile if a plugin has been installed?
vagrant
Solution
The Vagrant.has_plugin?(name) method returns true if a plugin has been installed.
Example:
unless Vagrant.has_plugin?("vagrant-some-plugin")
raise 'some-plugin is not installed!'
end

Problem
I would like to detect if a plugin has been installed, so I can add some useful debugging tips for users. I have tried the following code: ``` if config.vbguest config.vbguest.auto_update = true else puts "installing vagrant-vbguest plugin is recommended" end ``` However, Vagrant outputs `* Unknown configuration section 'vbguest'.` Is there a way I can detect whether a plugin has been installed?
