How to install geopandas library on macOS?

I suggest you create a brand new environment before starting.

Ensure that when you create a conda env, you don't use default packages. You will thank yourself later.

  conda create --no-default-packages -n geo_pandas python=3.7
  conda activate geo_pandas
  conda config --env --add channels conda-forge
  conda config --env --set channel_priority strict (This is optional)
  

install geopandas

  conda install -c conda-forge geopandas

You think that this will take care of all the dependencies for us. Not really! It appears that the version of fiona that geopandas depends on does not get installed correctly. (As of this writing, that is)

test geopandas

This will fail gloriously saying image not found.

OK, so install fiona again and test geopandas

conda install -c conda-forge fiona

This will downgrade some of the already install packages, don't worry.

Install jupyter (since i started from a clean slate, i didn't have jupyter either)

(geo_pandas) Shravan: airbnb_nyc$ conda install jupyter

OKAY, you also need "descrates"

Apparently, this module doesn't get install through package dependencies. So, when running your notebook, you will get an error saying "descrates" not found. At that point, close your eyes and run conda install -c conda-forge descartes. You will be all set.

(geo_pandas) Shravan: raw$ conda install -c conda-forge descartes
