I am attempting to install dedalus on a 2023 MacBook Pro with the Apple M2 Pro chip.

After completing step 5 on the installing dedalus guide page I received an error message. Here is everything printed after running the command, the command is included for reference. 

conda install -c conda-forge dedalus c-compiler "h5py=*=mpi*" "cython<3.0"

# Upgrade to Dedalus v3
conda uninstall --force dedalus
CC=mpicc pip3 install --no-cache --no-build-isolation http://github.com/dedalusproject/dedalus/zipball/master/

Hi George,

It looks like the issue is that the final pip3 command is hitting the system python (3.8), not the version from the conda environment. This might be a problem with some shell settings, i.e. using zsh instead bash, which may be the new default on macs. Can you try reactivating the environment and rerunning the final pip command, making sure you’re using pip/python from conda?

Thanks,
-Keaton
