Error in installing the library

[Himscipy]

Hi,
Following the installation instructions results in the following issue. Let me know how to resolve the installation issue.

conda create -n soupy -c conda-forge python=3.11 fenics==2019.1.0 petsc4py==3.19 matplotlib scipy jupyter

Hi @Himscipy, the installation issue appears to stem from the fact that you're using conda with the arm64 platform, while fenics is only available as an x86 package. Try configuring the environment as an x86 package by putting CONDA_SUBDIR=osx-64 before the conda call.

CONDA_SUBDIR=osx-64 conda create -n soupy -c conda-forge python=3.11 fenics==2019.1.0 petsc4py==3.19 matplotlib scipy jupyter

and then once built,

conda activate soupy
conda config --env --set subdir osx-64

This is now in the latest installation instructions. Please let me know if there are further issues.
