Here's what I'm seeing in the GRASS that I just installed from the same
installer. The commands at the terminal show me:
1. The location of the python being executed
2. The location of the pip being executed
3. Which error happens when I try to install pandas
4. Changing the shell to zsh
5. Checking whether that changed the python available
6. Error when I try to install pandas
As I suspected, the application Python is not able to use pip install to
install pandas. The next step is to determine how to
1) change the Python that builds with GRASS
2) give that Python access to the system framework libraries that allow things
to build
If it's feasible, the easiest way to use OSGEO things on Mac is with Docker
containers. Does that help at all?
