我目前正在使用 Python 的 Spyder,当我打开程序时出现此错误消息:错误:您缺少依赖项!
rtree>= 0.8.3:无(NOK)
请安装它们以避免出现此消息。
注意:Spyder 可以在没有这些依赖项的情况下工作,但是为了获得流畅的体验,我们强烈建议。
我试过 pip install rtree 并得到:

请指教我能做什么。到目前为止,Spyder 工作得很好,我只是不想在此过程中遇到问题。谢谢!

看起来 Rtree 需要未自动安装的libspatialindex ( https://libspatialindex.org )。似乎一些开发人员意识到了这个问题并正在着手修复:
https://github.com/Toblerity/rtree/issues/146 https://github.com/Toblerity/rtree/issues/147
用同样的问题来到这里,我不使用conda,无法安装libspatialindex使用pipenv:
# macOS Mojave 10.14.5
# python 3.7.4 (via pyenv)
Error: Command "python setup.py egg_info" failed with error code 1 in /var/folders/r7/2sx1wsvx0gj5x43wkmymg61w0000gq/T/tmpn09357tzbuild/rtree/

找到解决方案-spatialindex通过 Homebrew安装:
brew install spatialindex

然后pipenv install rtree成功了,现在geopandas工作顺利
希望它会有所帮助
