报错原因
VSCode的python扩展会使用debugpy库实现调试功能。在涉及qt组件加载时debugpy的qt_loaders.py会尝试加载imp库。而在python3.12及以后的版本中imp库被importlib取代因此 import imp语句会报错ModuleNotFoundError。
解决方法
出现问题代码位于qt_loaders.py的has_binding函数定义中 修改前
def has_binding(api):
#中间省略import imptry:# importing top level PyQt4/PySide module is ok...mod __import__(module_name)# ...importing submodules is notimp.find_module(QtCore, mod.__path__)imp.find_module(QtGui, mod.__path__)imp.find_module(QtSvg, mod.__path__)# we can also safely check PySide versionif api QT_API_PYSIDE:return check_version(mod.__version__, 1.0.3)else:return Trueexcept ImportError:return False对症下药既然在新版python中imp库不再有效为了兼容性先尝试import imp语句若无法导入imp包则进入catch分支import importlib修改代码如下

Turning interactive mode on.
