Created attachment 418683 [details] WIP patch
Talking with Don on Slack, I think markupsafe should be 1.1.1, I messed up version locking 2.0.0, which is an alpha version.

Python 3.9 seems to want to download the 2.0.0 version, probably due to compatibility. This patch though does clear it up and it does install successfully.
