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GUI。到目前为止，这确实非常成功，直到我在尝试调试gui时遇到一个奇怪的错误。我已经在脚本的开始以及各个点设置了一个断点，但是程序没有机会到达这一点。我也尝试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（无需调试）时，不会遇到任何这些错误。

Answer 1

我遇到了同样的问题，花了我一段时间，但我找到了适合我的解决方案。我相信发生的事情是调试器正在_pydevd_bundle.pydevd_cython目录中查找模块code。但是，由于您是在自己的code目录之外运行脚本，因此调试器将检查您的文件夹，发现它们不是模块，并引发错误。那将解释为什么删除__init__.py作品，因为调试器将不再混淆这两个目录。

因此，将您的代码目录重命名为其他目录，应该可以解决此问题，并保留初始化文件。
