How to fix "configure: error: libproj not found in standard or given locations." when installing {{sf}} on macOS?

Hi, and welcome!

Please see the FAQ: What's a reproducible example (`reprex`) and how do I create one? Using a reprex, complete with representative data will attract quicker and more answers. Not needed for this type of question.

You have two options:

  1. Decline the "compile from source" option and install the most recent binary version, which works just fine. Or
  2. Wait for the latest and greatest sf version to become available in binary before trying it out.

When I have a need to be on a later version than is currently avail in macOS in binary, I install it on one of my Linux machines. Also, consider that the very latest features for a package that a user hasn't yet become familiar with the basics of are unlikely to be needed. :grin:

This is what happens if you just say no:

  There is a binary version available but the source version is later:
   binary source needs_compilation
sf  0.8-1  0.9-0              TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) n
