python - 突然所有虚拟环境都失败了

Question

我使用 vscode，在这个特定的示例中我正在使用 Jupyter。昨天，我的工作做得很好。今天，我的venv坏了，所以我删除并重新开始：

python -m venv venv
./venv/Scripts/Activate

好的，所以我现在有了全新的 venv。因此，让我们尝试更新 pip：

python -m pip --upgrade pip

我得到这个错误：

Traceback (most recent call last):

好的，让我们尝试忽略这个设置的 jupyter。

pip install wheel
pip install juypterlab
pip install ipykernel

然后，当我尝试在 VSCode 中运行该笔记本中的单元时，我收到此错误：

Kernel died (code: 1). ModuleNotFoundError: No module named 'email.parser',

这到底是怎么回事？

我刚刚证明它会在 3.8 全局解释器实例上出错，即使我有其他笔记本正在处理它。我添加了该项目的屏幕截图。
