I am attempting to install the vagrant-vbguest plugin in Windows 7 from within cygwin 64.
$ 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 json (1.8.1), and Bundler cannot continue. Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
Performing the suggested step results in:
$ gem install json -v '1.8.1' Building native extensions. This could take a while... Successfully installed json-1.8.1 1 gem installed Installing ri documentation for json-1.8.1... Installing RDoc documentation for json-1.8.1...
Running the first command then fails in the same way.
