Vagrant experienced a version conflict with some installed plugins!
This usually happens if you recently upgraded Vagrant. As part of the
upgrade process, some existing plugins are no longer compatible with
this version of Vagrant. The recommended way to fix this is to remove
your existing plugins and reinstall them one-by-one. To remove all
plugins:

    rm -r ~/.vagrant.d/plugins.json ~/.vagrant.d/gems

Note if you have an alternate VAGRANT_HOME environmental variable
set, the folders above will be in that directory rather than your
user's home directory.

The error message is shown below:

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    vagrant (= 1.7.4) was resolved to 1.7.4, which depends on
      bundler (<= 1.10.5, >= 1.5.2)

  Current Bundler version:
    bundler (1.11.2)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (<= 1.10.5, >= 1.5.2)', which is required by gem 'vagrant (= 1.7.4)', in any of the sources.
