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，然后再安装rtree，已安装，没有问题，但是在尝试安装osmnx时发生了这种情况（实际上，在发现我需要安装geopandas之前，我曾尝试安装osmnx，在此给出此错误是为了向您提供尽可能多的信息）< / p>

我该怎么办（我不想安装anaconda，所以如果有一种避免使用anaconda的方法，我会非常高兴）？

任何帮助表示感谢，非常感谢

编辑：好的，我尝试了在问题中解释的与我的问题重复的步骤，我能够按照以下步骤安装fiona，但是当我键入pip install geopandas时，出现了这个新错误：

编辑2：即使在我尝试运行简单的Attempt.py时，cmd写道“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来安装地理空间依赖项可能真的很困难，这主要是由于Fiona的经验。如果可以使用conda，则强烈建议您遵循OSMnx documentation

中的安装说明

如果安装有任何问题，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
