title: rails mysql server error "could not find gem"
body: <p>When I try to run "rails server" on a new project it returns </p>
  
  <pre><code>Could not find gem 'mysql2 (&gt;= 0) X86-mingw32' in any of the gem sources listed in your Gemfile. 
  Run 'bundle install' to install missing gems.
  </code></pre>
  
  <p>I ran 'bundle install' but I'm getting the same error.</p>
  
  <p>I already had mysql installed from the xampp package, but my friend helped me install rails so I'm not sure how he configured it. I use Windows Vista.</p>
