Hi all,

I've not tried rendering MOOSE docs on my machine before, and was hoping to do so this morning. Unfortunately, when I run the moosedocs build, I get hit with an error like this on every .md file it touches:

MooseDocs.base.readers (Process-6):

I've attached the list of python modules I've got installed and their versions, and am running python 3.8.6.
