How can I install vagrant plugins on win8

Question

I haveinstalled vagrant(1.7.4) and virtualbox(5.0.2) on windows, then I downloaded precise32.box and put in inside the folder named vag_pre. After I entered this command line:vagrant up, it occured warning. Here is the codes:

Think@RESEARCH E:\vag_pre
$ vagrant box add base precise32.box
==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box 'base' (v0) for provider:
    box: Unpacking necessary files from: file://E:/vag_pre/precise32.box
    box: Progress: 100% (Rate: 2588k/s, Estimated time remaining: --:--:--)
==> box: Successfully added box 'base' (v0) for 'virtualbox'!

Think@RESEARCH E:\vag_pre
$ ls
precise32.box

Think@RESEARCH E:\vag_pre
$ vagrant init
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

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.

Warning: this Gemfile contains multiple primary sources. Using `source` more than once without a block is a security risk, and may result in installing unexpected gems. To resolve this warning, use a block to indicate which gems should come from the secondary source. To upgrade this warning to an error, run `bundle config disable_multisource true`.Gem::RemoteFetcher::FetchError: Errno::ECONNRESET: An existing connection was forcibly closed by the remote host. - SSL_connect (https://rubygems.org/gems/little-plugger-1.1.4.gem)

And I don't know how to install gem on win8.1, should I install ruby first? Thanks very much

To install a new plugin you need to run vagrant plugin install vagrant-vbguest.

as it seems you're having an issue with the ssl connection to https://rubygems.org, you should add the following parameter :

vagrant plugin install vagrant-vbguest --plugin-source http://rubygems.org
