Could not find generator 'delayed_job:active_record

Question

I'm trying to install this gem in rails app: https://github.com/collectiveidea/delayed_job

As instructed, I added this to my gem file, and ran bundle install:

gem 'delayed_job_active_record'

Then, upon running the command

rails g delayed_job:active_record

I get

Running via Spring preloader in process 4971
Expected string default value for '--jbuilder'; got true (boolean)
Expected boolean default value for '--markerb'; got :erb (string)
[WARNING] Please install gem 'therubyracer' to use Less.
Expected string default value for '--rc'; got false (boolean)
Expected string default value for '--helper'; got true (boolean)

Expected string default value for '--rc'; got false (boolean)
Could not find generator 'delayed_job:active_record'. Maybe you meant 'devise:controllers' or 'active_record:model' or 'devise:form_for'

What could be causing this?

Here is my gemfile for further reference:

If you're using spring you can find that functionality from new gems is not always available.

In this case you should do spring stop first.

spring stop
rails g delayed_job:active_record
