C++ 编译期间未找到QDialog

我请求您了解QT

您知道为什么在编译过程中moc文件无法从QT中找到include吗

我目前在Qt项目中有这个问题，错误是

“moc_设置Dialog.cpp:9:在moc_设置Dialog.cpp:9中包含的文件中： SettingsDialog.h:12:错误：“未找到QDialog”文件”

这是我的专业文件：

编译命令行时是什么样子的？和SettingsDialog.h代码？请至少发布SettingsDialog.h

的标题部分，如果没有设置Dialog\u h#定义SettingsDialog\u h#包含#包含#包含命名空间Ui{class SettingsDialog}；类设置Dialog:public QDialog{Q_OBJECT public:/***@brief settings dialog*@param parent*/explicit settings dialog（QWidget*parent=nullptr）

编译器的消息是：

在moc_settings dialog.cpp:9中包含的文件中：../../cashrister/includes/settings dialog.h:12:10：致命错误：“未找到QDialog”文件include
