我正在尝试在geolocation中使用离子本机插件ionic 4,但出现此错误:

  

无法编译。

     

./ node_modules/@ionic-native/geolocation/index.js找不到模块:   错误:无法解析“ rxjs / Observable”   'C:\ Projects \ ionic \ prayers \ node_modules \ @ ionic-native \ geolocation'

这是我的依赖项:

"dependencies": {
    "@angular/common": "6.0.9",
    "@angular/core": "6.0.9",
    "@angular/forms": "6.0.9",
    "@angular/http": "6.0.9",
    "@angular/platform-browser": "6.0.9",
    "@angular/platform-browser-dynamic": "6.0.9",
    "@angular/router": "6.0.9",
    "@ionic-native/core": "5.0.0-beta.14",
    "@ionic-native/geolocation": "^4.11.0",
    "@ionic-native/splash-screen": "5.0.0-beta.14",
    "@ionic-native/status-bar": "5.0.0-beta.14",
    "@ionic/angular": "4.0.0-beta.0",
    "@ionic/ng-toolkit": "1.0.0",
    "@ionic/schematics-angular": "1.0.1",
    "cordova-plugin-geolocation": "^4.0.1",
    "core-js": "^2.5.3",
    "rxjs": "6.2.2",
    "zone.js": "^0.8.26"
  },

这是我使用的代码:-

app.module.ts

import { Geolocation } from '@ionic-native/geolocation';
...
NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule],
  providers: [
    StatusBar,
    SplashScreen, Geolocation,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})

home.ts

import { Geolocation } from '@ionic-native/geolocation';
...
constructor(private geolocation: Geolocation) {}

2 个答案:

答案 0 :(得分:5)

您已安装rxjs 6.2.2,用于更改导入语句。

稳定的离子型天然离子仍在使用rxjs 5.x

您可以查看迁移指南here

您可以使用rxjs-compat

npm i rxjs-compat --save

或返回5.x版本。

另一种选择是将@ionic-native/geolocation版本更新为 5.0.0-beta14

就像您其他的离子本机插件一样,因为根据package.json,它应该使用rxjs 6.x

npm i --save @ionic-native/geolocation@5.0.0-beta.14

答案 1 :(得分:1)

我遇到了同样的问题,将Geolocation升级到5.0.0-beta.14时,我还不得不将导入路径更新为:

import { Geolocation } from "@ionic-native/geolocation/ngx";

OBS:对于其他导入,例如UniqueDeviceID,我还必须在导入路径中添加后缀/ngx
我认为由于Angular 6是必需的,所以需要后缀。
