After adding this plugin to a lektor site, the following appears and breaks the plugin to work:

Running lektor plugins remove lektor-tags before and after lektor plugins flush-cache is also not working.

Package was not registered with the project.  Nothing was removed.

The first snippet looks like a failure to install. Removing it after that wouldn't work because it isn't there to remove.

As for why your install failed, I wish your snippet contained your actual command. I don't see where tags==0.0.3 is coming from. As far as I can tell, the version in this repo was always 0.1, so where' you get 0.0.3? There is also no line matching long_description = open('description.rst', 'r').read() in the setup.py. I'm thinking you were installing something else entirely.

Closing this due to age and I think that your version was wrong. If something similar is still an issue, please raise another ticket.
