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.

Answer 2

As per documentation httpstan versions higher than 1.0.0 do not support Windows:

Requirements

Python version 3.7 or higher. macOS or Linux. C++ compiler: gcc ≥9.0 or clang ≥10.0.

Only solutions I found for now is to use Docker or VM .
