标签: angular ionic-framework ionic3 chart.js

我正在尝试在Ionic 3项目中使用chart.js,但是当我在“ app.module.ts”中导入ChartsModule时,它会生成错误。我收到此错误

对象(__WEBPACK_IMPORTED_MODULE_2_aangular_core))[«defineInjectable»])不是函数…

The error

...

import { ChartsModule } from 'ng2-charts';

@NgModule({
    declarations: [ MyApp ],
    imports: [
        BrowserModule,
        FormsModule,
        IonicModule.forRoot(MyApp),
        AngularFireModule.initializeApp(FIREBASE_CONFIG),
        AngularFireAuthModule,
        AngularFireDatabaseModule,
        ChartsModule
    ],

...

这是我的“ package.json”文件代码,如下所示: 这是下面的“ package.json”文件代码: 这是我下面的“ package.json”文件代码:
