我的应用程序似乎没有拾取我的角度材料/对话框模块。我该如何解决这个问题以使其正常工作？

Question

我想为我的角度应用程序使用两个材质ui组件。它们分别是MatDialog和MatDialogConfig。我不确定我是否把东西放错了地方，但基本上我所有的模块都能正常工作，除了这个模块。我的app.module.ts文件和组件course-dialog.component文件都有带有MatDialog和MatDialogConfig的导入语句，只是在运行程序时找不到模块。下面列出了它们。如何让我的编译器加载这些模块？app.module.ts

export class CoursesCardListModule { }

Answer 1

在您的模块中，您需要导入MatDialogModule，如下所示：

import { MatDialogModule } from '@angular/material/dialog';

文件中的导入将在组件中使用。

所以在你的模块中，你应该有这个导入：

@NgModule({
declarations: [AppComponent],
entryComponents: [],
imports: [
// here is the correct import
MatDialogModule, // instead of MatDialog and MatDialogConfig
HttpClientModule,
BrowserModule,
ComponentsModule,
....
