cap unicorn:restart (missing argument: -E)

[matthieupinte]

Hi, I experiment your gem since few hours, so I'm not sure is missed something or it's an issue for you. When I run cap unicorn:restart it's returning this:

INFO[b9e6e3c4] Running /usr/bin/env sudo service unicorn_appname_staging restart on 162.243.251.XXX

If you can help me to know what I missed? Thanks.

I think you should set rails_env variable in one of your project_root/config/deploy/[env].rb, here is a simple example for this:

set :rails_env, "staging"

@simoniong but it should not be necessary, since capistrano_rails sets the :rails_env for you automagically.
I ran into the same error and don't think, that setting this var in each environment's deploy settings is the correct way.

[matthieupinte]

@simoniong if you set explicitly the rails environment in your deploy configuration files: set :rails_env, "staging" working.

But why when you do cap staging unicorn:setup_initializer your rails environment is not "used"?
