vagrant plugin install vagrant-parallels

Installing the 'vagrant-parallels' 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 little-plugger (1.1.4), and Bundler cannot continue. Make sure that gem install little-plugger -v '1.1.4' succeeds before bundling.

when I change the --plugin-source

The error is the same. Then I try

gem install little-plugger -v '1.1.4'

回答1:

I have a stupid way first gem install little-plugger -v '1.1.4' in /Library/Ruby/Gems/2.0.0 and then copy

sudo cp -r gems/little-plugger-1.1.4/ /opt/vagrant/embedded/gems/gems/
sudo cp -r specifications/little-plugger-1.1.4.gemspec /opt/vagrant/embedded/gems/specifications
sudo cp -r doc/little-plugger-1.1.4 /opt/vagrant/embedded/gems/doc
sudo cp cache/little-plugger-1.1.4.gem /opt/vagrant/embedded/gems/cache

It worked. But what other convenient way can set the gem install path
