Heroku flask应用程序失败：找不到importlib.util模块错误

Question

我正在尝试使用Heroku部署Flask应用程序，并且我得到my_thread = new QThread; ThreadClass *my_threaded_class = new ThreadClass(); my_threaded_class->moveToThread(my_thread); // start and finish QObject::connect(my_thread, &QThread::started, my_threaded_class, &ThreadClass::scanAll); // https://stackoverflow.com/questions/53468408 QObject::connect(my_thread, &QThread::finished, my_threaded_class, &ThreadClass::stop); // finish cascade // https://stackoverflow.com/a/21597042/6411540 QObject::connect(my_threaded_class, &ThreadClass::finished, my_threaded_class, &ThreadClass::deleteLater); QObject::connect(my_threaded_class, &ThreadClass::destroyed, my_thread, &QThread::quit); QObject::connect(my_thread, &QThread::finished, my_thread, &QThread::deleteLater); my_thread->start(); 。我不明白为什么，因为我所有的模块都是最新的。有人知道如何解决此错误吗？

这是我正在使用的代码。代码构建良好，我似乎无法正确部署应用。
