• something tells me this might be because the pyenv activate is getting used?

$ wc /usr/local/miniconda3/bin/activate 
     125     483    3802 /usr/local/miniconda3/bin/activate
$ less /usr/local/miniconda3/bin/activate 
$ which activate
/Users/michal/.pyenv/shims/activate
$ 

• Going to try to modify the PATH...

$ which activate
/Users/michal/.pyenv/shims/activate
$ echo $PATH
/Users/michal/.pyenv/shims:/usr/local/miniconda3/bin:/Users/michal/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/TeX/texbin
$ export PATH=/usr/local/miniconda3/bin:/Users/michal/.pyenv/shims:/Users/michal/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/TeX/texbin
$ 
$ which activate
/usr/local/miniconda3/bin/activate
$ source activate blogplt
(blogplt) $

• Nice! That ^ worked. Just need to be aware of the PATH when deciding which VirtualEnv System to use ...
