Import error Django 2.2.5

[dennereed]

Hi there. With Python 3.7.6, Django 2.2.5, fastkml 0.11, I have an app that attempts to import fastkml in the view.py and this is raising an error. Oddly, the error does not occur on import into the Python console. For example:

Python 3.7.6 (default, Dec 30 2019, 19:38:26) [Clang 11.0.0 (clang-1100.0.33.16)] on darwin Django 2.2.5

import fastkml

No problem. But when I attempt to call it in my views.py I get error. The traceback looks like this:

looks like the last commit on fastkml/init.py might be the source of the problem. Removing the changes from that commit, i.e. the call to pkg_resources on line 28 resolves the issue. Not sure why importing pkg_resources is creating problems.
