Installing TA-Lib on Macbook - python-3.x

Question

I'm trying to get install TA-lib, but running into errors I don't understand.
I installed brew, and ran the following:
brew install ta-lib
That seemed to work because if I re-run that, I get a note that
ta-lib 0.4.0 is already installed and up-to-date
However, running pip3 install ta-lib results in the following errors. From googling around, this seems to happen when ta-lib wasn't installed first, but not sure how to address when the initial install seems to go fine.
pip3 install TA-lib
Collecting TA-lib
Using cached TA-Lib-0.4.19.tar.gz (267 kB)
Requirement already satisfied: numpy in /Users/mf/venv/lib/python3.8/site-packages (from TA-lib) (1.19.5)
Using legacy 'setup.py install' for TA-lib, since package 'wheel' is not installed.

I updated TA_LIBRARY_PATH & TA_INCLUDE_PATH after finding where brew was installing ta-lib, ran the following and pip3 install seemed to work properly, but I wasn't able to actually import it. After trying to re-install ta-lib, I get the same error as above.
export TA_LIBRARY_PATH=/opt/homebrew/opt/ta-lib/lib
export TA_INCLUDE_PATH=/opt/homebrew/opt/ta-lib/include
