[Bug]: on installation, "No Module named 'CMakeBuild'"

[khurlbutt]

PyBaMM Version

latest

Python Version

3.8.9

Describe the bug

I am trying to install PyBaMM on Mac OS. Running

-> brew install sundials && pip3 install pybamm

gives the error

"ModuleNotFoundError: No module named 'CMakeBuild'".

This is after succesfful install / update to sundials and during the attempt to install pybamm itself. Any advice or guidance on how to get pybamm installed would be much appreciated.

Steps to Reproduce

In terminal on Mac OSx 12.2 running Python 3.8 issue "brew install sundials && pip3 install pybamm".

Relevant log output

ModuleNotFoundError: No module named 'CMakeBuild'

Hi @khurlbutt, can you please post your full log output?

@martinjrobins it begins below (as a reminder, I issued "brew install sundials && pip3 install pybamm")

It looks like you have one of the newer apple M1 CPUs? If so we don't support these yet via installation from PyPI. I would recommend that you try installing from source, using the instructions here: https://pybamm.readthedocs.io/en/latest/install/install-from-source.html

[khurlbutt]

OK, thanks for that @martinjrobins. Issuing the final command "python3 setup.py install" gives the error below. Note that the other suggested methods of install, tox and pip, also give errors; I can include those as necessary. Thanks for your help.

[martinjrobins]

its not finding casadi in your python environment. Can you try pip install casadi before you run this command

[martinjrobins]

another option if you don't need the idaklu solver is to delete the pybind11 directory, that way it will skip building the idaklu solver which is where you are getting the error

[valentinsulzer]

Has this been solved?

[jaskiratsingh2000]

Is this still open?

[valentinsulzer]

We'll close it since we haven't heard back in a while
