[3-0-stable] Error in production: uninitialized constant Spree::StoreController

[givanse]

The server is able to start just fine in development but when passing the variable RAILS_ENV=production it doesn't start and shows:

better_spree_paypal_express-526d7f4f5bb9/app/controllers/spree/paypal_controller.rb:2:in `<module:Spree>': uninitialized constant Spree::StoreController (NameError)

The only issue with a similar error was reported in 2013 (#7) and it was related to spree_gateway.

Completely removing the gem (bundle clean --force), did not solve the problem.

Note: in development the server starts just fine

I have a same problem. gem works fine on dev, but crashes on staging with same error as above.

https://github.com/spree-contrib/better_spree_paypal_express/blob/master/app/controllers/spree/paypal_controller.rb#L2
PaypalController inherits from StoreController which is defined in spree_frontend gem. I'm only using spree_backend. Maybe that's the issue? But why is it working on development then?

Any ideas? @givanse, maybe you found a solution?

@nowakov sure, this gem requires StoreController, so also spree_frontend.
this dependency should be in the gemspec to avoid confusion

it's working in development because it has lazy loading, i think

[givanse]

I ended up downgrading to 2.X.

I don't know why I didn't think about trying to also install the frontend gem, shouldn't be that way I think.
