Django 2.1a1: cannot import name 'TOKEN_BLOCK'

[stefankoegl]

When trying to run my project with Django 2.1a1, I get the following error

I did not find anything in the (under development) release notes. Is this something that should be addressed in django_coverage_plugin, or should I report it to django instead?

Looks like django/django#9938 replaced this and related constants with an enum.

Now that #57 has been merged into master, this issue is now fixed.

I will be releasing the latest version later today.

Thanks to all of you for documenting the issue!

I have issued a release-candidate with the changes: https://pypi.org/project/django_coverage_plugin/1.6rc1/
