Installing PyCLD3 on an Apple M1 Mac

While building my work product on the fancy-schmancy M1 work Mac, I kept running into clang errors, when I did a pip install
Turns out, PyCLD3 would not build.
So I did it manually. This tip on Github did the trick
We need brew installed.
And then we run the following commands in a terminal …

  
brew install protobuf #install protobuf

# set various compiler flags
export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1
export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1
export CFLAGS='-I /opt/homebrew/opt/protobuf/include'
export LDFLAGS=-L/opt/homebrew/opt/protobuf/lib

# install pycld3
python3 -m pip install pycld3

And we’re set!
