Do you have a blas + lapack install? Unfortunately the error message "OpenBLAS or Netlib BLAS/CBLAS is required on all platforms except Windows, and was not found" is incorrect as a blas install is required on all platforms.
Oh also we don't have the wheels published for 3.13 yet I think, it's on my todo list!
I tried the scs-3.2.7-cp312-cp312-win_amd64.whl package and it works fine for Python 3.12 environment. Therefore, I guess this issue can be fixed once a whl is published for Python 3.13.
It seems that the Python 3.13 wheels are now available since the release of version 3.2.7.post2 (https://pypi.org/project/scs/3.2.7.post2/#files). For me, it's now possible to install scs in a Python 3.13 environment. @JoeyPhung @qiansen1386 if it works for you too, I think this issue can be closed.
