sunspot: Don't know how to build task 'sunspot:solr:start'

Hi everyone,

I actually just installed the Gem : gem 'sunspot_solr' gem 'sunspot_rails'

and I’m facing an issue. When I try to bundle exec rake sunspot:solr:start, I’m having the following error Don't know how to build task 'sunspot:solr:start'

I’m actually using Rails 4 and Ruby 2.0.0. I didn’t see anything in the documentation talking about the Gem with Rails 4 so I guess it might be incompatible.

Anyway, if you guys have any idea why it’s not working…

Thanks for the help
