安装 Geopandas 的问题

Question

I tried pip install geopandas

When I run that, I get this error:

Collecting geopandas

I also tried conda install -c conda-forge geopandas

In this case, everything runs fine, but when I try to run this one-liner:

import geopandas as gpd

I get this result:

ModuleNotFoundError: No module named 'geopandas'

I'm guessing that there is some kind of conflict with some other library that is installed, but it's just a guess, and I don't know for sure what the problem is. How can I get this thing to work? Thanks!!

Answer 1

You can try it

$ conda install -c anaconda pip
$ pip install geopandas
$ pip install Fiona

Answer 2

For me this installation worked (even without Anaconda). Get the GDAL package from here (Gohlke)

Install it with pip install GDAL_..._.whl

Upon installing the same error will occur, but no problem! Go to the system environment variables and create a new system variable and name it GDAL_VERSION and give it the value of the package version. Looks like this:

Then try to install GDAL again and it will work (maybe you need to restart the console). Then install geopandas with pip install geopandas and everything should work.
