Answer 1

I had the same problem trying to install PyStan at Windows 10 and found here (https://pystan.readthedocs.io/en/latest/upgrading.html#notable-changes) that last version PyStan (version 3) aren't available for windows anymore. Just for Linux and MacOS. I'll create a Linux Docker to solve it.

I found it too (https://github.com/facebook/prophet/issues/17#issuecomment-808769442) explaining the team are working at new release to solve another problem from PyStan 3.

Hope it help you too.
