调研方向

从 src/debugpy/_vendored/pydevd/pydev_ipython/qt.py 的第 15-17 行开始,检查 RuntimeError 格式字符串及其参数。如果可能,重现报告的 Qt API 错误,然后验证无效 API 路径引发的是预期的 RuntimeError,而不是 TypeError。

Issue

I'm getting a Failed to enable GUI event loop integration for 'qt' error when attempting to debug a PyQt application (I've seen the guiEventLoop parameter discussed elsewhere, but I can't find anything about what it actually does. Can anyone explain it?). However, the full traceback for the error seems to point to an additional bug in debugpy concerning these lines:

Abridged traceback:

  File "c:\Users\Andrew\.vscode\extensions\ms-python.debugpy-2024.6.0-win32-x64\bundled\libs\debugpy\_vendored\pydevd\pydev_ipython\qt.py", line 16, in <module>
    raise RuntimeError("Invalid Qt API %r, valid values are: %r, %r" %
                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: not all arguments converted during string formatting

Problematic lines:
