python - 无法在 VScode 中调试 Python

Question

每当我尝试在 VScode（甚至 Visual Studio）中调试任何 python 代码时，我都会在它到达第一行代码之前遇到错误（或者看起来如此）。大约 18 小时前，我能够在我的笔记本电脑和台式电脑上调试 VScode 和 Visual Studio，然后休息一下。截至约 4 小时前，我在尝试运行调试时一直遇到错误。我可以通过 python.exe 通过 cmd.exe 毫无问题地运行代码C:\Python\Python37-32\python.exe C:\Coding\Codecademy\Python\one.py。

我尝试卸载 VScode、Visual Studio 和 python，并删除了与任何 VScode 或 Visual Studio 相关的所有文件。然后我重新安装了 VScode 和 python 3.7，尽管终端中仍然出现错误。即使使用简单的print("Hello World").

我目前正在使用 Microsoft 的 Python 扩展，没有安装其他扩展。

错误代码如下：

更新：问题仍然存在，但我注意到另一个区域似乎引发了关于 python 的类似错误（与“队列”对象有关）。每当我尝试安装 linter 时，它都会在终端中引发以下错误：

尝试检查您的 python 版本当我尝试在 VScode 中运行我的 python3 代码时遇到了类似的错误。尝试在 vscode 中更改 python 版本。
