安装 OSMnx 和 GeoPandas 时出现错误消息

Question

您好，我正在尝试使用 pip install osmnx 和 pip install geopandas 安装 OSMnx 和 GeoPandas（根据此链接：https://geoffboeing.com/2016/11/osmnx-python-street-networks/）它说要使用 OSMnx，您必须先安装 geopandas 和 rtree，安装了 rtree没有问题，但是在尝试安装 osmnx 时发生了这种情况（实际上我在发现需要安装 geopandas 之前尝试安装 osmnx，我在这里给出这个错误是为了给你尽可能多的信息）

我该怎么办（我不想安装 anaconda，所以如果有办法避免 anaconda 我会很高兴）？

感谢您的帮助，非常感谢您

编辑：好的，我尝试了作为我的问题重复提到的问题中解释的步骤，我能够按照这些步骤安装 fiona，但是当我输入 pip install geopandas 时，我收到了这个新错误：

编辑 2：即使 cmd 在我尝试运行简单的 Attempt.py 时写了“成功安装 fiona”

import fiona

我收到了这条消息：

这也可能有助于解决我的问题

Answer 1

根据我的经验，使用 pip 安装地理空间依赖项可能非常困难，这主要是由于 Fiona。如果可以使用 conda，强烈建议按照OSMnx documentation中的安装说明进行操作

如果您在安装过程中遇到任何问题，请尝试使用 conda-forge 和严格的通道优先级在新的、干净的 conda 环境中安装 OSMnx：

conda config --prepend channels conda-forge
conda create -n ox --strict-channel-priority python=3 osmnx
