CalledProcessError: Command '['cmake', '--version']' returned non-zero exit status 1.

Hi all!

I am trying to run these fantastic notebooks but I constantly have the same issue when trying to create virtual environments or when just trying to install list_of_packages.txt, as instructed in the README.md

I am on macOS Ventura, M2 chip.

My issue is similar to that of Issue #10 but is a bit worse, it seems. Let me explain:

1. Let's consider one of the possible options for creating an environment. Say, we follow Option 2 (create a new environment with the latest Python version) as presented in the README.md.
2. One has to run the following code in the terminal: conda create -n FMNM python conda activate FMNM PACKAGES=$(tr '\n' ' ' < list_of_packages.txt | sed "s/arch/arch-py/g") conda install ${PACKAGES[@]} pip install -e .
3. I set up the right directory in the terminal (I have a copy of the notebook in a folder on my desktop).
4. Given the Issue ERROR: Failed building wheel for qdldl #10, I also installed CMake pip install CMake and I verified the version with cmake --version (version 3.27.2)
5. Now, hoping that all goes well, I decide to run the code of point (3.) but then I get the following subprocess error:

"subprocess.CalledProcessError: Command '['cmake', '--version']' returned non-zero exit status 1."
(some line above this message, I get "Building wheel for qdldl did not run successfully")

I am not 100% sure what this means, but I can't proceed with the installation.
Does any of you have an idea of what the issue could be? I am aware that is a very specific issue, but any suggestion is welcome!

Thank you in advance!

Hello.
Please, follow these steps:

• Remove the current virtual environment: conda remove -n FMNM --all
• Install cmake with homebrew. If you don't have homebrew, please install it.
• Try again the installation using the Option 1, that makes use of the environment.yml file.
• If it doesn't work, remove the environment and try the option 2 or the option 3.
• Run the commands one by one, and if the installation breaks, please let me know at which point.

A correct installation of CMake was key!
I checked and the notebooks run smoothly now. 🎉

Thank you so much @cantaro86 !!
