If you’ve migrated your site from earlier versions of Plone to the
latest ones in the 4.x series, or else have started using
plone.app.discussion earlier than that, you might have come across a
situation where comments on your site show user IDs as authors rather
than a user’s full name. If you see this anywhere, chances are your
comment’s migration didn’t go according to plan, and that the Creator
information didn’t get recorded correctly on the comment.
This is pretty trivial (and trivial to fix), but I’m chronicling it for
my knowledge as much as anyone else’s. The issue is that a given Python
egg is missing some form of files, most commonly the ‘docs’ directory in
my experience, because the build wasn’t configured correctly.
The error goes somewhat like this:
Getting distribution for 'my.theme'.
error: docs/HISTORY.txt: No such file or directory
An error occured when trying to install my.theme 1.5.0. Look above this message for any errors that were output by easy_install.
