在 Macbook Pro M1 蒙特利中安装 rtree==0.9.4

Question

我目前正在尝试在Python3.7.9 中安装rtree 0.9.4 版本。但是，我不断收到以下错误。不过，我可以安装任何版本的 rtree>=0.9.5。问题是我确实需要 0.9.4 版本。

大多数主题都与安装 libspatialindex 相关。我已经使用Homebrew安装了spatialindex，但仍然无法安装rtree==0.9.4。我应该降级我的 Python 版本还是类似的东西？我还按照“警告”中的建议更新了我的 pip 版本，但错误仍然相同。

Answer 1

我也遇到了同样的问题，只是不是在安装时出现的，而是在 MacOS Ventura 13.6.6 上导入 rtree 时出现的。如果您不准备自己从头开始构建 rtree，一种解决方案是设置 SPATIALINDEX_C_LIBRARY 如本拉取请求中所述。

您可以通过将以下代码添加到诸如 ~/.zshenv 文件之类的内容中来实现此目的，或者通过某种其他方式让该环境变量在您使用 rtree 或其他内容时持续存在将其作为像geopandas这样的依赖项：

export SPATIALINDEX_C_LIBRARY=/opt/homebrew/Cellar/spatialindex/1.9.3/lib

这使得上述错误对我来说消失了。
