【中文标题】构建包期间没有名为“版本”的模块【英文标题】:No module named 'version' during building package 【发布时间】:2021-10-05 20:16:12 【问题描述】:我正在尝试使用pyproject.toml
构建一个自定义python 包。我添加了一个setup.py
只是为了开发和可编辑的环境。 (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版本
当我运行python3 -m build
时出现此错误:
...

我不明白错误的来源,这似乎与我的代码没有链接。
【问题讨论】:
【参考方案1】:人们通常在一个模块中设置变量__version__
,一个名为version.py
的文件,以指定版本信息并使其可供全世界检查,详细解释见pep-0396。所以回溯可能表明你的包中缺少版本文件。
