无法安装osmnx

Question

我正在尝试使用pip在linux中安装osmnx库，我得到下面的错误。

在搜索之后，正如几篇文章中所建议的那样，我已经更新了pip和setuptools，也安装了shapely，但我得到了相同的错误。我正在尝试通过pip而不是conda进行安装。有没有人可以建议如何解决这个问题并安装库。

Answer 1

下面是我克服这个错误所遵循的过程。尝试升级你的setuptools。

pip install --upgrade setuptools，如果仍然面临同样的问题，请检查是否安装了osmnx的所有依赖项。在我的例子中，我必须通过pip安装rtree，这也依赖于我通过yum install spatialindex安装的spatialindex。然后是pip install osmnx，它工作得很好。

请注意，ubuntu和debian中的spatialindex是libspatialindex-dev。

也可以按照@gboeing在他的答案here中提供的说明进行操作。
