上图是Qt 的编译错误截图

这是错误的具体信息
其实就是两次建立工程的，昨天是手贱，手动选择建立quick2版本的QML工程，这样的工程在main.cpp中使用的和之前的是不一样的。
这是昨天的错误版的main.cpp
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl(QLatin1String("qrc:/main.qml")));
return app.exec();
}
这是今天的main.cpp
QApplication app(argc, argv);
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
对比一下就发现了吧，
下面截图是今天的正确运行方式
剩下的东西等我有时间在写
