undefined method `set_default' for main:Object

[jerefrer]

I get this error while performing any other task than deployment. For instance :

$ rake secret
rake aborted!
undefined method `set_default' for main:Object
/home/jeremy/.rvm/gems/ruby-2.0.0-p481/bundler/gems/mina-slack-bd023a63f945/lib/mina/slack/defaults.rb:2:in `<top (required)>'
/home/jeremy/.rvm/gems/ruby-2.0.0-p481/bundler/gems/mina-slack-bd023a63f945/lib/mina/slack.rb:1:in `require'
/home/jeremy/.rvm/gems/ruby-2.0.0-p481/bundler/gems/mina-slack-bd023a63f945/lib/mina/slack.rb:1:in `<top (required)>'

I don't know much about how gem are required by Rails so I don't know how to cleanly fix this.

The only way I found was to surround the content of all the lib/slack/defaults.rb and lib/slack/tasks.rb files in begin/rescue blocks. You can find my forked gem with this patch here : https://github.com/jerefrer/mina-slack

Years late, but have you tried adding require: false to the Gem's line in your Gemfile? Like:

gem 'mina-slack', require: false
