安装 Python geopandas 失败

Question

I'm trying to install geopandas. Have the following setup:

• Windows-64
• Anaconda2 (64-bit)
• Python 2.7

Have tried two things:

1)

pip install geopandas

This gives me the following error:

WindowsError: [Error 126] The specified module could not be found and Command "python setup.py egg_info" failed with error code 1 in c:\\users\\username\\appdata\\local\\temp\\pip-install-_kgeyw\\shapely\\

The solutions to the similar problem here suggest that it's because of the slashes in the path being converted. Not sure how to test this.

2)

anaconda search -t conda geopandas

I then search for the version of geopandas suitable for my setup (Windows-64):

conda install -c maxalbert geopandas

which produces the following error:

UnsatisfiableError: The following specifications were found to be in conflict:
 - geopandas
Use "conda info <package> to see the dependencies for each package

When I run the command conda info geopandas I get a list of geopandas version. Not sure how to proceed from here.

Answer 1

It is a common problem and the solution is to install all dependencies manually (as Geoff Boeing describes here: https://geoffboeing.com/2014/09/using-geopandas-windows/ )

First try to conda install -c conda-forge geopandas . If it doesn't work, do the following steps:

1. Download wheels for your Python version and OS for GDAL, Fiona, pyproj, rtree and shapely (eg from Gohlke)
2. Uninstall all OSGeo4W, GDAL, Fiona, pyproj, rtree and shapely packages
3. pip install the downloaded wheels in the following order: GDAL, Fiona, pyproj, rtree and shapely (for example pip install GDAL-1.11.2-cp27-none-win_amd64.whl )
4. Now you can pip install geopandas

Answer 2

I found the best/fastest way to be: create environment w/ geopandas then install jupyter notebook eg

• conda create -n python=3.6 geopandas
• conda install jupyter notebook

Answer 3

试试下面的代码：

conda install geopandas
