  <p>Any ideas as to why the Devise gem won't install after correctly adding it to the Gemfile and running the bundle install?</p>
  
  <p>I did have the server running at one point (rails server) and saw an article stating that attempting to install Devise whilst the server is up could cause strange issues.</p>
  
  <p>I've since tried again with the server down but no difference.  I'm sure this is probably happening due to something really simple that I overlooked in the setup, just not sure where else to look.</p>
  
  <p>Any advise or suggestions on where to look next would be great, thanks.  </p>
  
  <p>I've done testing using the command below but still received the same error:</p>
  
  <pre><code>leigh@leigh-VirtualBox:~/Projects/dev01$ bundle exec rails g devise:install
  Could not find generator devise:install.
  </code></pre>
  
  <p>The list of installed generators are below and Devise is not listed, how do I get it listed?</p>
  
  <pre><code>leigh@leigh-VirtualBox:~/Projects/dev01$ rails generate
  Usage: rails generate GENERATOR [args] [options]
  
  General options:
    -h, [--help]     # Print generator's options and usage
    -p, [--pretend]  # Run but do not make any changes
    -f, [--force]    # Overwrite files that already exist
    -s, [--skip]     # Skip files that already exist
    -q, [--quiet]    # Suppress status output
  
  Please choose a generator below.
