NoMethodError: undefined method `size' for nil:NilClass
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 vagrant-share (1.1.4), and Bundler cannot continue.
Make sure that `gem install vagrant-share -v '1.1.4'` succeeds before bundling.

After these error I was installed manually gem vagrant-share 1.1.4 but I discovered that vagrant has plugin vagrant-share 1.1.3 as system plugin:

# vagrant plugin update vagrant-share
vagrant-share (1.1.3, system)

The question: How install vagrant-sphere plugin in consistency way with vagrant 1.7.x?

Solution

I found the solution on answer of question: vagrant plugin install error gem install little-plugger -v '1.1.4' succeeds before bundling:

But in my case I need copy resource of vagrant-share gem:

gem install vagrant-share '1.1.5'
sudo cp -r gems/vagrant-share-1.1.5/ /opt/vagrant/embedded/gems/gems/
sudo cp -r specifications/vagrant-share-1.1.5.gemspec /opt/vagrant/embedded/gems/specifications
sudo cp -r doc/vagrant-share-1.1.5 /opt/vagrant/embedded/gems/doc
sudo cp cache/vagrant-share-1.1.5.gem /opt/vagrant/embedded/gems/cache

Then you can execute without problems: vagrant pluging install vagrant-vpshere
