离子cordova插件添加cordova- plugin -datepicker

我的module.ts课就像-

import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { IonicStorageModule } from '@ionic/storage';
import { AuthGuard } from './guards/auth.guard';
import { AuthenticationService } from './services/authentication.service';
import { HttpClientModule }    from '@angular/common/http';
import { NativeStorage } from '@ionic-native/native-storage/ngx';
import {EncrDecrService} from './services/encr-decr-service.service';

import {SortPageModule} from './pages/sort/sort.module';
import {FilterPageModule} from './pages/filter/filter.module';

import { RestoreAvailablePageModule } from './pages/restore-available/restore-available.module';

import { DatePicker } from '@ionic-native/date-picker/ngx';

@NgModule({

    IonicModule.forRoot(),
    AppRoutingModule,
    HttpClientModule,
    IonicStorageModule.forRoot(),

    {
      provide: IonicGestureConfig,
      useClass: IonicGestureConfig
  },
  ],

})
export class AppModule {}

我的错误越来越少-

src/app/app.module.ts中的ng错误:25:28-错误TS2307：找不到模块‘@离子型-本机/日期选择器/ngx’。ng 25从'@ionic-native/date-picker/ngx'；导入{ DatePicker }

我认为您应该首先使用以下命令卸载它：

npm uninstall --save @ionic-native/date-picker

然后使用下面的命令再次安装它：

npm install --save @ionic-native/date-picker@latest

这应该能行。不要忘记更新package.json文件并在module.ts文件中导入。
