But I have managed to download, from https://repo.anaconda.com/pkgs/main/win-64/, the file
matplotlib-base-3.3.2-py38hba9282a_0.tar.bz2
Is there any way to activate it, from Julia, using the Conda package?

I’m not sure. I use PyPlot/matplotlib on Linux, and it just works. On Linux you use system Python and I’ve added other packages through pip (i.e. bypassing Julia infrastructure), and matplotlib isn’t really different. Maybe you can do that too. I think you may be on Windows where Conda, not system Python, is used by default, and even then pip might be an option.

I do see what you may want to look into:

This is on master (and not yet a new version tagges), so you’ll need to do:

pkg> add Conda#master
