title: Could not locate Gemfile after executing "bundle install"
body: <p>Hey,
  I am completely new to Rails and just started created my first Project, following the Steps of a tutorial.</p>
  
  <p>I created the new Project using: <code>rails myapp</code>.</p>
  
  <p>Then I should execute <code>bundle install</code>, this did not work because bundler has not been installed, after an Update on Gems and installing bundler I have been able to execute <code>bundle install</code>, but every time I receive: Could not locate Gemfile</p>
  
  <p>I checked my project dir, it is true there is no Gemfile, but should this be created automatically or not?</p>
  
  <p>Thanks in advance</p>
