Cannot pip install ffnet on Big Sur #8

Closed johncoxon closed 3 years ago

johncoxon commented 3 years ago

Trying to install ffnet on Big Sur using gcc 10.2.0 (installed with homebrew), and getting the following errors in Terminal. How can I troubleshoot this?

John@Yavin ~ % pip install ffnet

I followed the instructions at this StackOverflow question and the issue has been resolved; so it's a macOS bug, not an ffnet one.
