python - 使用Pycharm调试PyQt gui时出现奇怪的错误

Question

我一直在使用 PyCharm 在 PyQt 中调试我的图形用户界面。到目前为止，这真的很成功，直到我刚才在尝试调试我的 gui 时遇到了一个奇怪的错误。我在脚本的开头以及各个点都设置了断点，但程序没有机会到达这一点。我也试过删除所有断点并运行调试但得到相同的结果。完整的回溯是:

有谁知道导致此错误的原因以及如何解决？当我正常运行代码(没有调试)时，我没有遇到任何这些错误。

Answer 1

我遇到了同样的问题，这花了我一段时间，但我找到了适合我的解决方案。我相信会发生什么，调试器正在目录 code 中寻找模块 _pydevd_bundle.pydevd_cython。但是，因为您是在自己的 code 目录外运行脚本，调试器会检查您的文件夹，发现它们没有模块，并抛出错误。这可以解释为什么删除 __init__.py 有效，因为调试器不会再混淆这两个目录。

因此，将您的代码目录重命名为其他名称应该可以解决问题并让您保留 init 文件。
