Q:

error ODB runtime version mismatch

Is there anyone that can resolve this issue for me? It is way above my pay grade. I have been struggling to install odb and it's dependencies for some time now, and had to resort to doing that manually vs Homebrew (which I normally use). This is where I am currently at. Not sure if there error is with my install, or something completely different.

A:

Use ODB 2.4.0 et al. This fixes it.
