Question

我正在使用Ionic documentation中指定的Native Storage插件，但是当我在设备或模拟器上部署时，我得到一个白色屏幕。当我将它连接到chrome后进一步检查＆gt;远程设备＆gt;检查。在控制台中我收到此错误错误错误：没有NativeStorage的提供程序！

任何指针？请帮忙

下面是我的错误日志：

Answer 1

这是吗？

1）将您的nativestorage插件导入apps.module.ts：

import { NativeStorage } from '@ionic-native/native-storage';

2）将Provider设置为：

providers: [
  NativeStorage ,
  {provide: }
  ]

希望它会有所帮助

Answer 2

删除条目：

 "ionic-native": "^2.5.1",

因为它是离子 - 天然3.x不需要的较老的离子 - 天然

同时尝试使用与@ionic-native/native-storage相同的@ionic-native/core版本。

"@ionic-native/native-storage": "3.7.0"

Answer 3

首先感谢所有的回复，@ Suraj我在你提到之后检查了package.json，我必须在依赖项下手动添加"cordova-plugin-nativestorage":"^2.2.2",然后干净并构建。现在它可以在Device和Emulator上正常工作。非常感谢你提起这件事!!

Answer 4

导入 NativeStorage 如下：

import { NativeStorage } from '@ionic-native/native-storage/ngx';

将其添加到提供者，如下所示：

providers: [NativeStorage]

完整示例：services.module.ts


import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { NativeStorage } from '@ionic-native/native-storage/ngx';
import { NativeStorageService } from './native-storage/native-storage.service';

@NgModule({
  declarations: [],
  imports: [
    CommonModule
  ],
  providers: [NativeStorage, NativeStorageService] 
})
export class ServicesModule { }

Ionic 2 - 错误：没有Native Storage的提供程序
