I am using macOS Monterey 12.2.1 on M1 chip and the installation failed.

I think I know the solution. You need to first brew install lzo to get the library headers.

I already install lzo in my computer by using brew install lzo.

CFLAGS=-I$(brew --prefix)/include LDFLAGS=-L$(brew --prefix)/lib pip3 install python-lzo

[damian-adelaide]

That worked for me. Thank you!

Now getting import error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/lzo.cpython-38-darwin.so, 0x0002): symbol not found in flat namespace '___lzo_init_v2'

So, why not upload wheel pkg to pypi ?
