Question

我正在尝试使用cordova-plugin-googleplus插件。

我已阅读其他帖子，说要将插件添加为提供商，并试图这样做无济于事。

当我尝试访问我的登录页面时，我发现堆栈跟踪错误：

运行时错误未捕获（承诺）：错误：没有GooglePlus提供商！错误：没有GooglePlus提供商！ atjectionError（http://localhost:8100/build/vendor.js:1590:86）在noProviderError（http://localhost:8100/build/vendor.js:1628:12）at ReflectiveInjector _。 throwOrNull（http://localhost:8100/build/vendor.js:3129:19）在ReflectiveInjector 。 getByKeyDefault（http://localhost:8100/build/vendor.js:3168:25）在ReflectiveInjector 。 getByKey（http://localhost:8100/build/vendor.js:3100:25）在ReflectiveInjector .get（http://localhost:8100/build/vendor.js:2969:21）at AppModuleInjector.get（ng：///AppModule/module.ngfactory.js）：332：145）位于AppModuleInjector.getInternal（ng：///AppModule/module.ngfactory.js：615：44）的AppModuleInjector.NgModuleInjector.get（http://localhost:8100/build/vendor.js:3936:44）at LoginPageModuleInjector.NgModuleInjector.get（{3 }}）

Answer 1

您需要将GooglePlus提供程序添加到AppModule（app.module.ts）

Answer 2

将GooglePlus添加到the App.module.ts对我有用

@NgModule({

  ...

  providers: [
    
    GooglePlus,
    
    
  ],
  bootstrap: [AppComponent]
})

未捕获（承诺）：错误：没有GooglePlus提供商
