vagrant plugin install failure using local gem

[lawrenceong]

Vagrant version

1.8.4

Host operating system

Ubuntu 16.04

Debug output

https://gist.github.com/lawrenceong/a587ccf77fdaa51edc573979391977a1

Expected behavior

The plugin installs without any issue.

Actual behavior

We get a bundler error when attempting to install the local plugin. Install works in Vagrant 1.8.1. Installing a remote plugin works without any issue.

Steps to reproduce

1. Install Vagrant 1.8.4
2. curl -O -L https://rubygems.org/downloads/vagrant-google-0.2.4.gem
3. vagrant plugin install ./vagrant-google-0.2.4.gem

I am experiencing the same issue. After upgrading to 1.8.4 'vagrant plugin install' can no longer install from local .gem files. Tested on OS X Yosemite and Ubuntu 16.04.

$ vagrant plugin install vagrant-hypconfigmgmt-0.0.1.gem 
Installing the 'vagrant-hypconfigmgmt-0.0.1.gem' 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:

Could not find gem 'vagrant-hypconfigmgmt (= 0.0.1)' in any of the gem sources listed in your Gemfile or available on this machine.

Tested with a random other vagrant plugin as well

$ vagrant plugin install pkg/vagrant-sshfs-1.1.0.gem 
Installing the 'pkg/vagrant-sshfs-1.1.0.gem' plugin. This can take a few minutes...

I had the similar issue with installing local gem in 1.8.4. Thanks for fixing again in 1.8.5.
