https://github.com/JuliaPy/PyCall.jl#specifying-the-python-version To force Julia to use its own Python distribution, via Conda, rather than whatever is installed on your system, simply set ENV["PYTHON"] to the empty string "" as described above. Second, the errors are saying something about fonts, but I can't figure out > what they are saying. I am also confused by the "permission denied" error: Hard to say. Try checking the permissions of the files listed by `fc-list`... Maybe something was installed with `sudo` that should not have been.
