建议您只pip install .从源代码安装包,但这不会编译任何 Cython 代码。执行此操作的最佳方法是什么?
Cython文档仍然建议使用setup.py,但我找不到任何更好的建议。看来开发人员安装(pip install -e .)确实编译了 Cython 文件,或者您可以python setup.py build_ext --inplace在运行后进行编译pip install .。这两个选项都不理想,所以我想知道是否有建议的替代方案。
编辑:
包 setup.py 文件包含以下代码,该代码应编译 Cython 文件:
try:
import numpy
from Cython.Build import cythonize
cython_files = ["farm/rasters/water_fill.pyx"]
cython_def = cythonize(cython_files, annotate=True,
compiler_directives={'language_level': str(sys.version_info.major)})
include_dirs = [numpy.get_include()]
except ImportError:
cython_def = None
include_dirs = None

我相信如果您保留setup.py但添加pyproject.toml. https://cython.readthedocs.io/en/latest/src/userguide/source_files_and_compilation.html中对此进行了描述。
这是他们给出的示例pyproject.toml文件:
[build-system]
requires = ["setuptools", "wheel", "Cython"]
