angular - Ionic 4 native 插件地理定位给我 "Module not found: Error: Can' t 解析 'rxjs/Observable'"

Question

我正在尝试在 ionic 4 中使用 ionic native 插件 geolocation 但我遇到了这个错误:

Failed to compile.

./node_modules/@ionic-native/geolocation/index.js Module not found: Error: Can't resolve 'rxjs/Observable' in 'C:\Projects\ionic\prayers\node_modules\@ionic-native\geolocation'

这是我的依赖:

"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:-

应用程序模块.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]
})

首页.ts

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

Answer 1

您安装了 rxjs 6.2.2，导入语句发生了变化。

稳定的ionic-native仍在使用rxjs 5.x .

可以查看迁移指南here .

您可以使用 rxjs-compat

npm i rxjs-compat --save

或者回到 5.x 版本。

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

与您的其他 ionic 原生插件一样，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
