rtree: Build fails on OS X

Even though this is closed, i landed here, but found the best solution in a different issue, not #74, the solution was simply brew install spatialindex (https://github.com/gboeing/osmnx/issues/3)

Surprisingly the brew install spatialindex seems to be not the solution. (anymore?) The error persisted.

brew install spatialindex Warning: spatialindex 1.9.3 is already installed and up-to-date

pip3 install rtree

As it concerns my problem I have the solution:

1. Install spatialindex with MacPorts: sudo port install spatialindex
2. Setting the Library Path: export DYLD_LIBRARY_PATH=“/opt/local/lib” 2a) or even better: export DYLD_FALLBACK_LIBRARY_PATH=“/opt/local/lib”
3. Install Rtree with pip: pip install Rtree
4. For permanent use you have also to add the “DYLD_LIBRARY_PATH” or “DYLD_FALLBACK_LIBRARY_PATH” to the file “.bash_profile”

Actually, I want to correct my comment.

Python 3.7.7 + brew install spatialindex works perfectly.
