MacOS上Python 3.7中Basemap的构建错误——来自Cython？

我一直在拼命尝试为Python 3.7重新安装Basemap，在执行

sudo python3 setup.py build

时，我不断遇到以下一长串错误：

在这一点上，我很确定问题来自Cython，正如这里指出的，调用了错误版本的Cython，但我不知道如何“重新生成C源代码”。我尝试了

cythonize--force src/_geoslib.pyx

，但我得到的结果是

cythonize

不存在。 你知道会发生什么以及如何修复吗

---

注意：如果我使用

sudo python setup.py build

，它调用python 2.7而不是3.7，则Basemap工作正常。

我也遇到了同样的问题。正如DavidW在评论中首先说的，我需要安装cython。pyshp也失踪了：

pip3 install cython
pip3 install pyshp

但是，也没有安装swig。所以我需要：

brew install swig

然后我必须通过pip安装basemap：

 pip3 install -U git+https://github.com/matplotlib/basemap.git

---

注意：我已经手动安装了geos-3.3.3，因此我不确定通过github安装的pip是否也会安装，您可能只需要安装Cython（最好使用您的系统包管理器程序，但如果安装失败，

pip安装Cython

）让cythonize正常工作。@DavidW重新安装

cython

解决了这个问题。真不敢相信这么简单。。。谢谢！对于python 3.9和Mojave，这对我不再适用：-(
