title: another error faced when installing snorby on linux
body: <p>When installing snorby, I need to use this line:</p>
  
  <pre><code>sudo bundle exec rake snorby:setup
  </code></pre>
  
  <p>When executing this, a problem occurred:</p>
  
  <pre><code>rake aborted!
  There was an error while trying to load the gem 'delayed_job'.
  Gem Load Error is: undefined method `yaml_as' for Module:Class
  Did you mean?  yaml_tag
  </code></pre>
  
  <p>(PS: It is said that when using bundler, psych is used which prevents delayed_job from working properly)</p>
  
  <p>Any help is appreciated</p>
