Pyinstaller 无法启动我的 .exe（没有模块“pydantic.deprecated.decorator”）

Question

我用 pyinstaller 编译了代码以生成 .exe，但是当我启动它时，它告诉我找不到模块“pydantic.deprecated.decorator”。 这似乎合乎逻辑，因为我对这个名字一无所知。所以我不知道该怎么做才能解决这个问题

我已经尝试重新安装 pydantic

The above exception was the direct cause of the following exception:

我也遇到过类似的错误消息。对我来说解决这个问题的是添加隐藏的导入。

通过以下隐藏导入，问题就消失了：

pyinstaller --hidden-import=pydantic --hidden-import=pydantic-core --hidden-import=pydantic.deprecated.decorator app.py
