[bernardoiconpro]

Hello,

While installing prophet 1.1 on Windows I got this error:

Running setup.py develop for prophet

Compiling cmdstanpy model

Same installation process on Linux works fine.

Tried downgrading cmdstanpy to 1.0.1 and it still happens. This installation process, prior to prophet 1.1, worked fine as well.

I typically try to install with Conda. Do you have an C++ compiler installed that cmdstanpy can use?

This should be resolved by more recent updates
