Well, it might be worth poking them and seeing if you get any response.

What happens if you create a venv using conda?  Is there some particular 
reason you're using Anaconda but not using its tools for managing 
virtualenvs?  I get it that pyenv should work, but it might be useful to 
isolate it further to tell if its just pyenv, or something else.  I 
don't have any experience with pyenv myself, sorry.
