python3 -m build 给出 ModuleNotFoundError：没有名为“pathlib2”的模块

Question

我正在尝试构建一个 Python 包，但出现以下错误。

* Creating virtualenv isolated environment...
* Installing packages in isolated environment... (setuptools >= 40.8.0, wheel)
* Getting dependencies for sdist...
Traceback (most recent call last):

ModuleNotFoundError: No module named 'pathlib2'

ERROR Backend subprocess exited when trying to invoke get_requires_for_build_sdist

我已经安装了pathlib2。解决办法是什么？

根据该build软件包的官方文档，它没有稳定的兼容性

https://pypa-build.readthedocs.io/en/latest/installation.html#compatibility

您可以尝试切换到旧版本的python（推荐3.9）并重试，理想情况下，这应该可以解决错误，因为在回溯中，错误似乎源自setuptools（它将自动恢复到旧版本，并使用旧版本）蟒蛇版本）

注意：您还需要在新的 python 版本中重新安装构建

如果您遇到任何问题，请告诉我。
