Clip vignette is failing upon build

[lwasser]

if you run the plot_clip.py vignette with the most recent version of geopandas and earthpy it is failing when you plot the data. The failure message is below. it's oddly not failing when i build docs locally but i see the issue when i run the code.

Traceback (most recent call last):
