Question

我正在尝试在运行python3.7.7的macOS计算机上安装rtree。在geopandas文档中，它指示macos安装ddo时不包含rtree的“二进制轮子”（实际上不确定这是什么意思）。

我按照网站https://libspatialindex.org/#download上的说明进行操作，并使用cmake安装了软件包。当我进入VScode的终端并运行命令时 python3 -m pip install rtree rtree已下载，但无法安装并产生错误消息：

为解决以下问题而采取的步骤： -根据先前对类似问题的答案的建议，通过自制程序安装了postgresql

我将libspacialindex东西安装在与项目相同的目录中。这是问题所在吗？我是否缺少为此所需的一些重要包装？

我们非常感谢您的帮助，如果您需要更多信息，请告诉我。

Answer 1

首先通过brew安装spaceindex，然后通过pip安装rtree：

brew install spatialindex

pip install rtree

从libspacialindex安装Rtree以在geopandas中使用.clip（）
