title: how to include all project gems into the gemfile?
body: <p>I work as a developer supporting several apps built in Rails, often I need to install gems that are not included into the gem file.</p>
  
  <p>Last day I build a project and when I try to run it on another computer I experienced some issues with missing gems, a lot actually and I didn't know where to get a list of all the missing gems or how to install them.</p>
  
  <p>The question is, is there a way to include all the gems that the project needs into the gem file so next time someone try to run it on another computer it will be enough to use the comand <code>bundle install</code>.</p>
