Dear Stan experts,

I am trying to install cmdstanpy on a win10 computer, however there is some warning in installing cmdstan.

import cmdstanpy
cmdstanpy.install_cmdstan()

After I download the cmdstan file and set the path. There is some warning in compling the stan model:

If you are using gcc from conda, install cmdstan from conda-forge
conda install cmdstan -c conda-forge
I’m not sure why is that cut line triggered and I still have not find a way to install it from conda. It comes with RTools.
              
To build cmdstan in conda we use 3 extra packages beyond just gcc and make:
- m2-filesystem   
- m2-sed             
- m2-coreutils     
I’m pretty sure cut is in m2-coreutils
              
update:  the problem is coming from the lib TBB Makefile which references cut - looks like conda-forge install is the way to go for Windows.
as cut is definitely part of coreutils, assuming it’s in m2-coreutils - GNU Coreutils 9.0
