rails - running production mode locally = No such file to load - config/environment

Question

I am trying to run locally in production mode with:

$ RAILS_ENV=production rails s

But I get:

/home/durrantm/.rvm/gems/ruby-1.9.3-p194@linker/gems/activesupport-3.1.8/li
b/active_support/dependencies.rb:306:in `rescue in depend_on': No such file
 to load -- /home/durrantm/Dropnot/webs/rails_apps/linker/app/assets/../con
fig/environment (LoadError)

I can create a brand new rails 3.1.8 app and do RAILS_ENV=production rails server and I don't get this problem.

I can also do rails s and that runs the server fine in development mode without error.

I can also do RAILS_ENV=development rails s and that runs the server fine in development mode without error.

fwiw, my app was originally a rails 2.3 app so perhaps I am missing something that's been added or changed in rails ?

I do have the config directory with an environment.rb file. Perhaps the way it's being referenced is wrong somehow?

I added config.assets.enabled = true to config/application.rb but it didn't help (didn't expect it to as that is asset compilation, but it was a difference I found!).

Answer 1

Changed a few things. One of the main ones were to enable static assets locally in config/environments/production.rb when trying to run it locally (only) and revert that before pushing to a production web server. I didn't know that.

Answer 2

seems like your old assets directory lived in other place (maybe in public ) and now it is in app/assets , but it doesn't know about it and some files try to load environment.rb . just double check assets dir.
