我试图构建一个自定义python包，与pyproject.toml。我添加了一个setup.py只是为了一个开发和可编辑的环境。(参见https://snarky.ca/what-the-heck-is-pyproject-toml/)pyproject-toml文件:
[build-system]
requires = ["setuptools == 44.1.1", "wheel"]
build-backend = "setuptools.build_meta"
[tool.pytest.ini_options]
testpaths = ["tests"]
我用python3 -m pip install --upgrade build升级了python构建
当我运行python3 -m build时，我得到这个错误:
...

我不明白错误的来源，这似乎与我的代码没有链接。
人们通常在模块(一个名为version.py的文件)中设置变量__version__，以指定版本信息，并使其可供全世界查看，详细说明请参见pep-0396。因此，回溯可能表明包中缺少版本文件。
可能，它在构建pyproject时读取setup.py(或setup.cfg等)。(只使用setuptools作为[build-system]??) .
你可以写&;from version importversion";你的设置里还有别的东西吗?
删除setup.py或将setup.py重命名为setup_ .py，例如
我Env .
- setuptools: 67.6.0
[build-system]
requires = ["setuptools", "setuptools_scm"]
