Angular 意外值';Matsnakbar&x27;由模块导入';AppModule';。请添加@NgModule注释
我想利用Matsnakbar在事件完成时显示通知。我在我的应用程序模块中导入了Matsnakbar,下面是我的app.module.tsAngular 意外值';Matsnakbar&x27;由模块导入';AppModule';。请添加@NgModule注释,angular,angular-material,Angular,Angular Material,我想利用Matsnakbar在事件完成时显示通知。我在我的应用程序模块中导入了Matsnakbar,下面是我的app.module.ts ... import { MatSnackBar, MatSnackBarConfig, ... } from '@angular/material'; ... @NgModule({ declarations: [...], imports: [MatSnackBar, MatSnackBarConfig, ...], pr
...
import { MatSnackBar,
MatSnackBarConfig, ...

...
@NgModule({

imports: [MatSnackBar, MatSnackBarConfig, ...],
providers: [...],

entryComponents: [...]
})
export class AppModule {
}
下面是my package.json:

下面是我得到的错误:

我正在使用angular material 5.0.0,是否需要使用其他版本来使用Matsnakbar 您需要导入
import { MatSnackBarModule } from "@angular/material";
并将其添加到进口项下
@NgModule({
imports: [
MatSnackBarModule,
],
providers: [
],
})
参考这里是对我有效的方法:
(之前我有导入错误,如
文件'angular/app/node_modules/@angular/material/index.d.ts'不是模块。
app.module.ts
中导入matsnakbarmodule
:
import { NgModule } from '@angular/core';
import { MatSnackBarModule } from '@angular/material/snack-bar'; // <= import the module: MatSnackBarMODULE
@NgModule({
declarations: [
],
imports: [
MatSnackBarModule, // <= add it to import list
],
import { MatSnackBar } from '@angular/material/snack-bar'; // <= ⚠️ import the class with path 'material/SNACK-BAR'
// […]
export class AppComponent {
constructor( private _snackbar: MatSnackBar ) { // <= add it to constructor
}
// Use it the way you like it
fooBar() {
const snack = this._snackbar.open('Hello', 'Action');
snack
.onAction()
.subscribe(() => {
// Action...
});
}
}
是的,我的不好。添加此导入后,工作正常,非常感谢!
