VSCode Python：枚举已安装的包时出错

Question

我长期成功的 VSCode Python 设置莫名其妙地崩溃了。

请问下面的错误是什么意思？首先推荐的Python 3.12找不到_tkinter。我尝试安装较旧的版本并得到这个。我也无法使用 pip，它说“外部管理环境”。我迷路了。

Answer 1

安装后修复importlib-metadata并debugpy在我的venv

Answer 2

这为我解决了这个问题（来自https://github.com/microsoft/debugpy/issues/1379）：

在 site-packages 下找到 debugpy/common/log.py （按照您在输出中看到的路径）。找到该文件中的行：

吞咽异常（“枚举已安装的软件包时出错。”）}

将其替换为：swallow_exception（“枚举已安装的软件包时出错。”，level =“info”）

令人难以置信的是，这还没有发布。

Answer 3

至少对于您显示的跟踪中的消息来说，它看起来与枚举已安装的软件包时的错误非常相似（至少通过跟踪）。#1379，尽管它是关于 Visual Studio 的调试。如果是同样的问题，根据维护者的说法，您可以忽略该消息，并且 debugpy 仍然可以正常工作。在更高版本的 debugpy 中，应将该日志消息分配给“info”日志级别。
