Install on MacOS build failed

[alexthemonk]

Hi,
So I was trying to install pyre2 on my Mac following the steps described in the Installation.
And I encountered the following error when I tried to do the install.
The same error message occurs if I do pip3 install re2

Could you please help me with this?

Thank you for your time.

$ python3 setup.py install
running install
running build
running build_ext
building 're2' extension
creating build
creating build/temp.macosx-10.9-x86_64-3.8

(I removed all the warnings for unreachable code and explicit value assignment for simplity)

There's an active (and updated) fork available here: https://github.com/andreasvc/pyre2 that builds fine on the CI macos runners. take a look at the files in.github/workflows but essentially all you should need is brew to install re2 and then build away...
