Ionic framework 在模块ts中输入提供程序时出错

当我试图在提供程序中导入

nativepagetransition

时，它显示了一个错误

import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';
import { LinkPage } from '../pages/link/link';
import { NativePageTransitions } from '@ionic-native/native-page-transitions';

import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';

@NgModule({
declarations: [
MyApp,
HomePage,
LinkPage,


],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage,
LinkPage

],
providers: [
StatusBar,
SplashScreen,
 NativePageTransitions,


 {provide: ErrorHandler, useClass: IonicErrorHandler}
 ]
 })
 export class AppModule {}

错误是

Type ‘NativePageTransitionsOriginal’ is not assignable to type ‘Provider’.
Type ‘NativePageTransitionsOriginal’ is missing the following properties from type ‘FactoryProvider’: provide, useFactory [2322]]

您安装了最新的

@ionic native/native page transitions

（v5+）

然后您应该从

@ionic native/native page transitions/ngx

import { NativePageTransitions } from '@ionic-native/native-page-transitions/ngx';

---

如果为项目类型安装了错误的本机插件版本，则会出现此错误

检查ionic.config.json中的项目类型

如果类型为“离子角”，则安装4.x.x版本

范例

npm i -s @ionic-native/native-page-transitions@4.20.0

如果类型为“角度”，则安装5.x.x-beta版本

npm i -s @ionic-native/native-page-transitions@5.0.0-beta.24

注意：

We have to import native modules from @ionic-native/module-name/ngx directory.
import { NativePageTransitions } from '@ionic-native/native-page-transitions/ngx';

仅当使用角度6时，才在导入结束时添加ngx

import { NativePageTransitions } from '@ionic-native/native-page-transitions/ngx';

如果没有，则从app.module.ts和app.component.ts中的导入中删除ngx

import { NativePageTransitions } from '@ionic-native/native-page-transitions';

参考：

爱奥尼亚4+中的所有本机模块和服务已移动到模块的ngx目录。

We were importing NativePageTransitions from @ionic-native/native-page-transitions
import { NativePageTransitions } from '@ionic-native/native-page-transitions';

像

离子3中的：

We were importing NativePageTransitions from @ionic-native/native-page-transitions
import { NativePageTransitions } from '@ionic-native/native-page-transitions';

现在在爱奥尼亚4+：

We have to import native modules from @ionic-native/module-name/ngx directory.
import { NativePageTransitions } from '@ionic-native/native-page-transitions/ngx';
