I'm getting a wierd build error -

Configuration error:
There is a programmable error in your configuration file:

Are you able to import pandas normally? That error doesn't seem directly related to the docs

[mitzimorris]

agreed, not directly related to the docs. it's more of an install/config thing.

here's what I did - from home directory of cmdstanpy, version develop:

conda create --name stan --clone base
conda activate stan
python --version
pip3 install -e .[all,docs,test]

shouldn't this give me everything I need to build the docs?

[WardBrian]

I think you'd be missing cmdstan.

But the --clone base is suspect to me - if you already had a copy of pandas (potentially a broken one, for whatever reason) you'd end up with it in here as well.

[mitzimorris]

OK, the problem is that you need to install pandas via conda - installing pandas using pip doesn't get the libraries needed for dateutil.

Installing python-dateutil via pip didn't help either.
