Installing FastText on an M1 Mac
# May 5, 2022
We rely on FastText in some of our NLP microservices. Since upgrading to an M1 Macbook, these dependencies have failed to build wheels.

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for fasttext
After some digging, the default C headers that are shipping with XCode are causing a definition conflict. Removing them fixes the problem. We move these to a temporary folder so we can restore them later, since they are functional for most of the other clang system installs.
sudo mv /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include_tmp
pip install fasttext
sudo mv /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include_tmp /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include
And we have a successful install:
Successfully built fasttext
