Unable to install plugin

[shubhamrajvanshi]

While installing plugin I get below error. Can someone help me or let me know if it is a known issue and if there is a workaround. I am getting this on Mac with OS X

vagrant plugin install vagrant-openstack-provider Installing the 'vagrant-openstack-provider' 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 (1.7.7), and Bundler cannot continue. Make sure that gem install json -v '1.7.7' succeeds before bundling.

I have experienced same issue but I couldn't install yet. I could install the plugin with Vagrant 1.7.4 which is older version. You can get from the below URL. Let try it! https://releases.hashicorp.com/vagrant/

@sawahashi2000 recommendation was the only solution that worked for me (without a lot of work). just went back to version 1.7.4...unfortunately that's the only easy solution until this is upgrade for v1.8.

I confirm the issue, and that installing Vagrant 1.7.4 solves the problem.
