title: WKHTMLTOPDF path in ROR application
body: <p>I am using wicked_pdf gem for HTML to PDF conversion. As per the descriptions in Github, I installed everything correctly. But I am getting a runtime error -</p>
  
  <p><b>RuntimeError (Bad wkhtmltopdf's path: /usr/local/bin/wkhtmltopdf):
    app/controllers/orders_controller.rb:46:in `create</b></p>
  
  <pre><code>`44 @count = Item.count(:qty)
  45  @temp = Item.where(:received =&gt; true).count()
  46  render  :pdf =&gt; "Bill" ,
  47  :template =&gt; 'orders/create.pdf.erb', # Excluding ".pdf" extension.
  48  page_height:  100,
  49  page_width:   80`
  </code></pre>
  
  <p>and wkhtmltopdf is installed in my system at /usr/local/bin/wkhtmltopdf</p>
  
  <p>It is specified that the path for wkhtmltopdf should be where it's already installed.</p>
  
  <p>I am not able to figure out what the problem is.</p>
