title: How to fix Shebang warning in Ruby
body: <p>When I execute any rails command in my project, I'm receiving this warning:</p>
  
  <pre><code>/home/vagrant/.rvm/rubies/ruby-2.5.3/bin/ruby: warning: shebang line ending with \r may cause problems
  </code></pre>
  
  <p>I tried to install another Ruby version, but the warning is the same.
  I'm using the same Ubuntu version of the developer.</p>
