Visual Studio代码python调试timeou

Question

我遵循微软的指南Getting Started with Python in VS Code，但只能在调试模式下运行一次——下面的运行总是会遇到超时问题。在

这是hello.py

msg = "Hello World"
print(msg)

这是launch.json，它基本上只添加了"stopOnEntry": true，因此在调试期间将在代码的第一行停止：

^{pr2}$

因此，我的第一轮调试成功了，Visual Studio代码中的终端显示：

Microsoft Windows [Version 6.1.7601]

C:\Playground\vscode\py\ms>c:/Playground/vscode/py/ms/env/Scripts/activate.bat
(env) C:\Playground\vscode\py\ms>cd c:\Playground\vscode\py\ms && cmd /C "set "PYTHONIOENCODING=UTF-8" && set "PYTHONUNBUFFERED=1" && c:\Playground\vscode\py\ms\env\Scripts\python.exe c:\Users\drlren\.vscode\extensions\ms-python.python-2019.5.18875\pythonFiles\ptvsd_launcher.py --default --client --host localhost --port 58792 c:\Playground\vscode\py\ms\hello.py "
Hello World

但是，如果我再次单击debug按钮，它卡住了，显示一个错误对话框：

[Window Title]
Visual Studio Code

[Content]
timeout

[Open launch.json] [Cancel]

，vscode内的终端显示：

(env) C:\Playground\vscode\py\ms>cd c:\Playground\vscode\py\ms && cmd /C "set "PYTHONIOENCODING=UTF-8" && set "PYTHONUNBUFFERED=1" && c:\Playground\vscode\py\ms\env\Scripts\python.exe c:\Users\drlren\.vscode\extensions\ms-python.python-2019.5.18875\pythonFiles\ptvsd_launcher.py --default --client --host localhost --port 58798 c:\Playground\vscode\py\ms\hello.py "

怎么了？我该怎么解决呢？在

Answer 1

我解决了这个问题，将终端从“bash”改为“commandprompt”（cmd）。在
