UnsatisfiableError when installing on windows

@ocefpaf I'm sorry I always bring up problems for you. OSMnx install via conda-forge is broken on Windows due to an UnsatisfiableError.

@ocefpaf I'm sorry I always bring up problems for you. OSMnx install via conda-forge is broken on Windows due to an UnsatisfiableError.

It is probably the other way around, conda-forge was supposed to make the life of scientist easier by removing the packaging problem from their day-to-day operations :smile:

The problem here is that gdal never had icu explicitly declared and the pin update broke it. I'm rebuilding all the working versions of gdal today. 2.4.1 should be already OK, 2.4.2 is in https://github.com/conda-forge/gdal-feedstock/pull/314 and 3.0.1 is next. I'll test it on Windows before closing this.

@gboeing I don't have a windows machine to check but I re-built the gdal packages that should (hopefully) fix this. Can you test it again?

[ocefpaf]

Got a Windows machine. This one is working again!

@ocefpaf thanks, I'm moving cross country this week but will test again soon as I can.
