This is unlikely the source of your problem, but I've seen it recommended to use at least setuptools version >= 0.6c10. See ​t:TracDev/DevelopmentEnvironmentSetup#Geteasy_install.

This issue is generally a result of updating the plugin while the trac process is still running.

Restart the trac process and it should work.

This is not a problem with the tags code itself.
