尝试安装caropy-python Anaconda时出错

Question

我正试图在Anaconda安装中安装caropy，但它不起作用。以下是错误消息。如何安装此软件包？我尝试使用进行安装

pip install cartopy 

和

conda install -c conda-forge cartopy  

两者都会出现以下错误：

Building wheels for collected packages: cartopy

Anaconda给了我这些错误：

conda install cartopy
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

现在它只是坐在那里旋转。

我安装了geos软件包。我不知道为什么它找不到安装。

Answer 1

这为我在Linux Mint系统中解决了这个问题。我可以看到OP的系统是Windows，所以不确定它是否也适用于他们。但对于在ubuntu/linux上登陆的用户来说，

我们需要先安装libgeos-dev:

sudo apt install libgeos-dev

从https://techoverflow.net/2021/08/13/6348/。

这似乎提供了上面提到的"geos_c.h"文件。

在这之后，pip install cartopy对我来说工作正常。
