Hi @slamcole!
Check out this part of the error message:
Looks like something isn't right with your environment. It could be that it is "incomplete" (missing dependencies), or, your environment variables could be "polluting" the environment with .
One thing that jumps out at me is this:
It looks like you have manually installed 2019.7 into a 2018.11 virtual machine. I suspect something has gone wrong with that. Can you run the command env and paste the results here? Thanks! :qiime2:
