Installing Rtree from libspacialindex to use .clip() in geopandas - python-3.x

Question

I am attempting to install rtree on my macOS machine running python3.7.7. In the geopandas documentation, it indicates that macos installs ddo not include "binary wheels" (not sure what this means honestly) for rtree.
I followed the instructions on the website https://libspatialindex.org/#download and installed the packages using cmake. When I go to my terminal in VScode and run the command
python3 -m pip install rtree rtree is downloaded, but it fails to install yielding the error message:
ERROR: Command errored out with exit status 1:

Steps taken to resolve:
- installed postgresql via homebrew as suggested by previous answers to similar questions
I installed the libspacialindex stuff in the same directory as my project. Is this where the problem is? Am I missing some crucial package needed for this?
Any help is greatly appreciated, let me know if you require more info.

Answer 1

First install spatialindex via brew, then rtree via pip:
brew install spatialindex
pip install rtree
