问题描述

在用Angular CLI 1.0.0-beta.11-webpack.9-1构建的Angular 2.0.0-rc.7 + Angular Material 2.0.0-alpha.8-1应用程序中，从rc.5 + alpha.7-4升级(通过1.0.0-beta.11-webpack.8 NG CLI)后，出现以下错误:

In my Angular 2.0.0-rc.7 + Angular Material 2.0.0-alpha.8-1 application built with Angular CLI 1.0.0-beta.11-webpack.9-1, I get the following error after upgrading from rc.5+alpha.7-4 (via the 1.0.0-beta.11-webpack.8 NG CLI):

我的package.json依赖项是:

  "dependencies": {
    "@angular/common": "2.0.0-rc.7",
    "@angular/compiler": "2.0.0-rc.7",
    "@angular/core": "2.0.0-rc.7",

    "@angular2-material/toolbar": "2.0.0-alpha.8-1",
    "@angular2-material/tooltip": "2.0.0-alpha.8-1"
  },

和

  "devDependencies": {
    "@types/jasmine": "^2.2.30",
    "angular-cli": "1.0.0-beta.11-webpack.9-1",
    "codelyzer": "~0.0.26",
    "jasmine-core": "2.4.1",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "4.0.5",
    "ts-node": "1.2.1",
    "tslint": "3.13.0",
    "typescript": "2.0.2"
  }

我的main.ts是:

import './polyfills.ts';

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModule } from './app/';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule);

这是我在app.module.ts中的@NgModule定义:

@NgModule({
  declarations: [
    AppComponent,
    // other application-specific components...
    PageNotFoundComponent,
  ],
  imports: [
    BrowserModule,
    CommonModule,
    ReactiveFormsModule,
    MdButtonModule,
    // other MD modules...
    MdTooltipModule,
    OverlayModule,
    PortalModule,
    RtlModule,
    routing        // application routing
  ],
  providers : [
    Title,
    MdIconRegistry,
    // set of application-specific providers...
  ],
  entryComponents: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {

}

有什么想法吗?

编辑(2018年5月):

OVERLAY_PROVIDERS现在已弃用.改用OverlayModule

Edit (May 2018):

OVERLAY_PROVIDERS is now deprecated. use the OverlayModule instead

import { OverlayModule } from '@angular/cdk/overlay';

@NgModule({
  imports: [
      OverlayModule
  ],
  declarations: [...],
  providers: [...],
  bootstrap: [...]
})
