安装 OSMnx 和 GeoPandas 时出现错误消息

Question

您好，我正在尝试使用 pip 安装 osmnx 和 pip 安装 geopandas 来安装 OSMnx 和GeoPandas(根据此链接：https://geoffboeing.com/2016/11/osmnx-python-street-networks/( 它说为了使用 OSMnx，您必须首先安装 geopandas 和 rtree，安装了 rtree 没有问题，但这发生在尝试安装 osmnx 时(实际上我在发现我需要安装 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(我不想安装蟒蛇，所以如果有办法避免蟒蛇我会很高兴(？

任何帮助表示赞赏，非常感谢

编辑：好的，我尝试了问题中提到的步骤，作为我的问题的重复，我能够按照以下步骤安装fiona，但是当我输入pip安装geopandas时，我遇到了这个新错误：

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

import fiona

我收到此消息：

这也可能有助于解决我的问题

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

如果您在安装时遇到任何问题，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
