Getting the "C extension is not installed" error #244

Open mike-lawrence opened 6 years ago

mike-lawrence commented 6 years ago

Hi there, I'm on macOS 10.13.4, running python 3.6.5 installed via brew install python. I've tried installing billiard via pip (pip3 install billiard) as well as downloading the source and running python3 setup.py install, but after both I'm getting the "C extension is not installed" error when I run billiard.forking_enable(0). Any ideas? In case it matters, I have both clang (via xcode-select) & gcc-7 (via brew) installed. Below is the output from the manual install attempt.

Could be MacOS related? Can you try on a VM with a Linux OS?
