  After l execute that command l get this error :</p>
  
  <pre><code>Bundler failed to load and return this error:
  
  cannot load such file -- bundler/setup
  
  you may need to uninstall or upgrade bundler
  </code></pre>
  
  <p>After this l uninstall bundler and install it again it didn't work . </p>
  
  <p>l tried to upgrade it as well but it said that all packages are up to date .</p>
