我想利用MatSnackBar在事件完成时显示通知 . 我在我的app模块中导入了MatSnackBar，下面是我的app.module.ts
...
import { MatSnackBar,
MatSnackBarConfig, ...
} from '@angular/material';
...
@NgModule({
declarations: [...],
imports: [MatSnackBar, MatSnackBarConfig, ...],
providers: [...],
bootstrap: [...],
entryComponents: [...]
})
export class AppModule {
}
下面是我的package.json：
{
"@angular/animations": "^5.1.0",
"@angular/cdk": "^5.0.0",
"@angular/cli": "^1.6.1",
"@angular/common": "^5.1.0",
"@angular/compiler": "^5.1.0",
"@angular/compiler-cli": "^5.1.0",
"@angular/core": "^5.1.0",
"@angular/forms": "^5.1.0",
"@angular/http": "^5.1.0",
"@angular/language-service": "^5.1.0",
"@angular/material": "^5.0.0",
"@angular/platform-browser": "^5.1.0",
"@angular/platform-browser-dynamic": "^5.1.0",
"@angular/router": "^5.1.0",
"@swimlane/ngx-charts": "^7.0.1",
"@types/jasmine": "^2.8.2",
"@types/jasminewd2": "^2.0.3",
"@types/node": "^8.0.56",
"angular2-datatable": "^0.6.0",
"core-js": "^2.5.1",
"d3": "^4.10.0",
"ng-http-loader": "^0.2.0",
"ng2-charts": "^1.6.0",
"ng2-handsontable": "^1.0.3",
"rxjs": "^5.5.5",
"zone.js": "^0.8.18"
}
以下是我得到的错误：
compiler.js:485 Uncaught Error: Unexpected value 'MatSnackBar' imported by the module 'AppModule'. Please add a @NgModule annotation.

我正在使用角度材料5.0.0，我是否需要使用其他版本才能使用MatSnackBar？
