I cannot uninstall the redmine plugin. I typed below as this redmine page describes.
rake redmine:plugins:migrate NAME=plugin_name VERSION=0 RAILS_ENV=production
And remove the plugin from plugin directory. When redmine restarted, it shows error screen. If I put Redmine Bitbucket back to plugin directory, it works again...
I used Redmine Bitbucket. The plugin is good. But I wanted to try uninstall it.
Some new redmine plugins have problem like this?
My redmine version is Redmine 2.1.4.stable.
I solved myself.
The problem is not on this plugin. I just set my Gemfile.lock's owner as root. I changed the ownership. I can remove this plugin. I will try to use this plugin again.
