I cannot uninstall the redmine plugin. I typed below as [this redmine page](http://www.redmine.org/projects/redmine/wiki/Plugins) 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](http://www.redmine.org/plugins/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.
