导入时我遇到以下错误

import geopandas as gpd

我已经使用anaconda安装了geoPandas，但是当我尝试运行它时，它显示了上述错误。 运行时

conda list

我正在接收

运行以下内容后:

conda install -c conda-forge fiona shapely pyproj rtree
conda install pandas
conda install -c conda-forge geopandas

你可以尝试运行以下命令：conda install -c conda-forge fiona shapely pyproj rtreeconda install pandasconda install -c conda-forge geopandas - Ari Cooper-Davis

我已经按照您的指示运行了程序，并编辑了我的问题，附上了现在得到的输出。 - Arshad

尝试创建一个最小安装的新conda环境，看看是否可以正常运行。我无法在我的“root” conda安装中运行“geopandas”，但是在一个新的、最小的“conda”环境中它可以正常工作。 - cd98

Answer 1

问题是由于fiona和gdal依赖不兼容引起的。通过conda卸载geopandas解决。它也会卸载fiona。 执行conda uninstall geopandas; 执行conda install fiona=1.6 先执行conda search fiona并查看其是否适用于您的Python版本。如果不适用，请为该Python版本创建新环境。(例如：create -n py35 python=3.5 anaconda)

然后执行pip install geopandas 最后，尝试import geopandas并查看您是否仍然会遇到错误。

Answer 2

我在MacOs Mojave 10.14中遇到了同样的问题。我发现解决方法是通过pip安装geopandas而不是使用conda。

pip install geopandas
