Unable to install SSCHA with ERROR: python setup.py egg_info did not run successfully / ERROR:metadata-generation-failed

[fengjiajia2023]

Dear developers,

I'm trying to install SSCHA on my CentOS (Intel-based) by Anaconda, as instructed in https://sscha.eu/download/, but when I enter "pip install cellconstructor python-sscha tdscha" the following error occurs:

---

    `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
    of the deprecation of `distutils` itself. It will be removed for
    Python >= 3.12. For older Python versions it will remain present.
    It is recommended to use `setuptools < 60.0` for those Python versions.

The python version is 3.11.11 and numpy version is 1.23.5,
Also, I tried with other versions of numpy and python but still filed to install.

I appreciate your support.

Best regards,
Jiajia

Hi, this is most likely a mismatch in the setuptools version, try running

pip install --force-reinstall setuptools==64

And then try to run again

pip install cellconstructor python-sscha tdscha
