I am trying to install (with pip install) on a mac BigSur a python package that needs gfortran.
The package was last updated in 2020.
I initially did
brew install gcc
and that brought in gfortran, but my pip install failed with some fortran errors.
My theory is that I need to revert to an older (circa 2020) version of gfortran.
I did
brew install gcc@8
but when I run
gfortran --version
it doesnt find gfortran.
I am a beginner with brew. Not sure what am I missing in these install games.
>Solution :
You are halfway there. Run these now
ln -s /usr/local/bin/gfortran-8 /usr/local/bin/gfortran
ln -s /usr/local/bin/gcc-8 /usr/local/bin/gcc
