Raspbian wheel/improved install instructions

[proximous]

It would be nice if you could offer a Raspbian wheel.

Barring that, it would be nice if you could update your install instructions to indicate that when installing from pip without a wheel, PROJ needs to be installed and a reference to https://proj.org/install.html provided.

It would also be nice for a clearer error message about this. I got:

ERROR: ...
Proj executable not found. Please set PROJ_DIR variable.

Prehaps something like:

ERROR: ...
Proj executable not found. Please install Proj (https://proj.org/install.html) and/or set PROJ_DIR variable.

Further, it would also be nice to list the PROJ version compatibility for the different pyproj releases. After running apt install proj-bin, my pip install pyproj still failed with:

ERROR: Minimum supported proj version is 6.2.0, installed version is 4.9.3.

It took a bit of digging through commits to find that I needed pip install pyproj==1.9.6 for compatibility with 4.9.3. Some simple compatibility chart would be nice.

Anyway, not complaints. Just hoping to inspire some enhanced install instructions to help others with this.

Sounds useful. Are you familiar with how to generate one?

For reference, here are the current installation instructions:
https://pyproj4.github.io/pyproj/stable/installation.html

Compatibility Matrix:
PROJ <= 5.2, pyproj <= 1.9.6
PROJ 6.0+, pyproj 2.0-2.1
PROJ 6.1+, pyproj 2.2-2.3
PROJ 6.2+, pyproj 2.4+

All good ideas. Would you like to update the docs with this information?

Looks like they have them here: https://www.piwheels.hostedpi.com/project/pyproj/ for pyproj 1.9.6. However. it looks like builds failed for pyproj 2+ on their wheel page. Submitted an issue: piwheels/packages#60

Wow! I didn't even realize I was using piwheels. Thanks for pointing that out and filing the issue!

Not a problem. Thanks for the suggestions!

Closing for preference to the piwheels issue.
