Hello, when I try to run the command "python setup.py build maven bdist_wheel", I'm getting the following issue. I attached my terminal output but the last line of the error is:

      **203 warnings and 1 error generated.
      error: command 'gcc' failed with exit status 1**

I have python 2.7 and 3.7 and 3.8 installed, but my python is set to 3.8 being the main version:
Python 3.8.3 (default, Jul 2 2020, 11:26:31)

I do have gcc installed
(base) ➜ ~ gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-

My overall goal is to get snappy working from ESA.
