MacOS 上 Python 3.7 中的底图构建错误——来自 Cython？

Question

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，我继续运行进入这个长长的错误列表：

在这一点上，我很确定问题出在 Cython 上，因为调用了错误版本的 Cython，正如此处指出的：https://github.com/matplotlib/basemap/issues/414，但我不知道如何 "regenerate the C sources"。我试过 cythonize --force src/_geoslib.pyx 但我发现 cythonize 不存在。关于可能发生的事情以及如何解决它的任何想法？

注意：底图在我 sudo python setup.py build 时工作正常，它调用 Python 2.7 而不是 3.7。

Answer 1

我遇到了同样的问题。正如 DavidW 在评论中所说的那样，我首先需要安装 cython。 pyshp 也丢失了：

pip3 install cython
pip3 install pyshp

但是swig也没有安装。所以我需要：

brew install swig

然后我不得不通过 pip 安装底图：

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

注意：我已经手动安装了 geos-3.3.3，所以我不确定通过 github 的 pip 安装是否也会安装

Answer 2

我在尝试使用 mac catalina 在 python 3.8.12 上安装 kmc2 时遇到了同样的问题。我通过 git 克隆 kmc2 存储库并在安装安装之前手动对 pyx 文件进行 cythonize 修复。
