I did: heroku plugins:install git://github.com/galetahub/rails-ckeditor.git
And got
Could not initialize rails-ckeditor: uninitialized constant ActiveSupport
Are you attempting to install a Rails plugin? If so, use the following:
Rails 2.x:
script/plugin install git://github.com/galetahub/rails-ckeditor.git
Rails 3.x:
rails plugin install git://github.com/galetahub/rails-ckeditor.git
my gemfile:
source :rubygems
gem 'rails', '2.3.8'
gem 'authlogic', '2.1.6'
gem 'addresslogic', '1.2.1'
gem 'searchlogic', '2.4.19'
gem 'subdomain-fu', '0.5.4'
gem 'ckeditor', '3.4.3'
DerNalia,
If I'm understanding you correctly I think you are misinterpreting what the heroku plugin install function is for. It's not for installing Rails plugins, it's for install plugins for the heroku command, like the heroku_colorize_console plugin. To install a plugin for your Rails application for Rails 2 you would use
script/plugin install git://github.com/galetahub/rails-ckeditor.git
This would install plugin into your vendor/plugins directory in your application and be initialized based on it's init.rb file (which is executed automated when the site loads). Your heroku app would have it accessible once you commit the changes and deploy back up to heroku.
See http://devcenter.heroku.com/articles/using-cli-plugins for more details about the Heroku command and the plugins function.
