title: vagrant up command issue
body: <p>I am new with Vagrant. My supervisor want me to run a website. First of all he told me to install VirtualBox and Vagrant. He sent me bootstrap.sh and Vagrantfile files. He told me to copy this in a folder called "data_repo". After that he told me to run "vagrant up" command from "data_repo". I did that but it is giving me following error:</p>
  
  <pre><code>A Vagrant environment or target machine is required to run this
  command. Run `vagrant init` to create a new Vagrant environment. Or,
  get an ID of a target machine from `vagrant global-status` to run
  this command on. A final option is to change to a directory with a
  Vagrantfile and to try again.
  </code></pre>
  
  <p>Could you please let me know the way to fix it?  </p>
