Unable to execute 'gcc-8': No such file or directory error: command 'gcc-8' failed with exit status 1. PySIT package installation

Question

I am trying to install a package called PySIT to be run with Python, and have followed the instructions on this install page (https://pysit.readthedocs.io/en/latest/install.html) using pip on my terminal to install PySIT.

I am using macOS Catalina for this, and have Anaconda installed on my computer.

This is the output I get on my terminal when I run the command: python setup.py install

gcc-8 -fno-strict-aliasing -I/Users/KBrindha/anaconda2/include -arch x86_64 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/KBrindha/anaconda2/lib/python2.7/site-packages/numpy/core/include -Ipysit/solvers/fd_tools -I/Users/KBrindha/anaconda2/include/python2.7 -c pysit/solvers/constant_density_acoustic/time/scalar/solvers_wrap.cxx -o build/temp.macosx-10.6-x86_64-2.7/pysit/solvers/constant_density_acoustic/time/scalar/solvers_wrap.o -O3 -fopenmp -ffast-math

unable to execute 'gcc-8': No such file or directory error: command 'gcc-8' failed with exit status 1

Any help on how to bypass this issue or install gcc-8 would be appreciated. For further information, I have Xcode and Xcode Command Line Tools installed in my computer. I also have "just" gcc (not gcc-8) installed at /usr/bin/gcc.

The authors inserted fixed names for compilers right into their setup.py. This is a bug and I recommend to report it.

Meanwhile you can clone the repository or download source code, extract it, edit setup.py and remove or replace these fixed names. Then build with the command pip install .
