感谢：https://github.com/pypa/setuptools/issues/4476#issuecomment-2236111062的这个回复。

先上软件包细节：

python 3.10.12
pyinstaller 6.6.0
setuptools 75.1.0
pip 24.2

具体报错：

PS F:\todo> pyinstaller -D -i "icon.ico" myscript.py

具体情况：

用Py写了一个todo组件，使用pyinstaller打包时出现上述报错。打包指令：

pyinstaller -D -i "icon.ico" todo.py    

排查问题发现直接输入pyinstaller之后，就会出现上述报错。问题原因尚不明确，推测是软件包版本导致的包导入问题。

解决方法：

安装backports-datetime-fromisoformat

pip install backports-datetime-fromisoformat

版本号：

backports-datetime-fromisoformat 2.0.2
