[英]What is the best replacement for python setup.py install when Cython needs to be compiled?
使用最新版本的setuptools時, python setup.py install
命令已被棄用(有關詳細信息,請參閱https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html )。
(venv) [jon@dev02 py38]$ python setup.py install
running install

建議直接pip install.
從源代碼安裝 package,但這不會編譯任何 Cython 代碼。 這樣做的最佳方法是什么?
Cython文檔仍然推薦使用setup.py
,我找不到更好的建議。 似乎開發人員安裝 ( pip install -e.
) 確實編譯了 Cython 文件,或者您可以在運行 pip install 后python setup.py build_ext --inplace
pip install.
. 這些選項都不是理想的,所以我想知道是否有建議的替代方案。
編輯:
package setup.py 文件包含這段代碼,它應該編譯 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
使用python setup.py install
時,farm/rasters 目錄包含以下文件:
water_fill.c
water_fill.cpython-38-x86_64-linux-gnu.so
water_fill.html
water_fill.pyx
安裝時使用pip install.
,該目錄不包含 .so 文件,當我們嘗試運行 water_fill 測試時,我們得到這樣的錯誤
________________________________ TestFlowDown1D.test_distribute_1d_trough_partial_3 _________________________________
farm/rasters/tests/test_flood_enhance.py:241: in test_distribute_1d_trough_partial_3
actual_arr = water_fill.water_fill_1d(arr, additional_value)
E AttributeError: 'NoneType' object has no attribute 'water_fill_1d'
我相信如果保留 setup.py 但添加 pyproject.toml,警告應該消失 go。 https://cython.readthedocs.io/en/latest/src/userguide/source_files_and_compilation.html中描述了如何執行此操作。
這是他們給出的示例 pyproject.toml 文件:
[build-system]
requires = ["setuptools", "wheel", "Cython"]
