How can I install Anaconda aside an existing pyenv installation on OSX?

Question

Sincerest apologies if this is easily found elsewhere, but although I found a number of posts with pyenv and Anaconda explanations, none addressed this issue specifically. H

Not super familiar with conda but I do use pyenv a lot.

Pyenv has its own virtualenv manager that you can use. You can always check which virtualenv version is active with:

pyenv versions

You should see something like:

  system
  20190814_125309
* 3.7.4 (set by /home/tzhuang/.pyenv/version)
  3.7.4/envs/20190814_125309
  3.7.4/envs/buildmaster-sandbox
  3.7.4/envs/HEAD
  3.7.4/envs/myenv
  3.7.4/envs/sandbox
  buildmaster-sandbox
  HEAD
  myenv
  sandbox

Where the * indicates the currently active virtualenv (this can be set using pyenv global like you mentioned). You can manually activate any virtualenv with:

pyenv shell

Eg.

pyenv shell sandbox

Then running pyenv versions gives:

  system
  20190814_125309
  3.7.4 (set by /home/tzhuang/.pyenv/version)
  3.7.4/envs/20190814_125309
  3.7.4/envs/buildmaster-sandbox
  3.7.4/envs/HEAD
  3.7.4/envs/myenv
  3.7.4/envs/sandbox
  buildmaster-sandbox
  HEAD
  myenv
* sandbox

It's generally a good idea to install any packages you want into a new virtualenv instead of the global virtualenv. It makes it easier to debug environment/dependency issues should you run into any.
