Rails Web application could not be started
<p>Getting this error even when I create a new project. I installed Ruby and RoR through RVM</p>

<pre><code>cannot load such file -- /var/lib/gems/2.3.0/gems/passenger-5.0.30/src/ruby_supportlib/phusion_passenger (LoadError)

<p>I think I found that the problem is in the directory of the gems. I do not know how to change it on Ubuntu</p>
