大佬教程收集整理的这篇文章主要介绍了node.js – 离子应用程序无法在链接包中找到提供程序,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
我的服务包模块如下所示:
import { NgModule } from '@angular/core'; import { ApiService } from './api.service'; import { AuthenticationService } from "./authentication.service"; import { CognitoUtil,CognitoCallback,LoggedInCallback } from "./cognito.service"; import { DocumentsService } from "./documents.service"; import { TagService } from "./tag.service"; import { UseRSService } from "./users.service"; import { AwsUtil } from "./aws.service"; @NgModule({ declarations: [ ApiService,AuthenticationService,CognitoUtil,AwsUtil,DocumentsService,TagService,UseRSService ],providers: [ AwsUtil,ApiService,TagService ] }) export class MyAppServicesModule { }
包的index.ts文件如下所示:
export { MyAppServicesModule } from './myapp-services.module';
{ "compilerOptions": { "target": "es2016","module": "commonjs","declaration": true,"outDir": "out","rootDir": "src","experimentalDecorators": true },"exclude": [ "node_modules","out" ] }
的package.json
{ "name": "@myapp/services","version": "1.0.0","description": "My App services","main": "index.js","scripts": { "test": "test" },"author": "","license": "ISC","devDependencies": { "@types/node": "^8.0.19","typescript": "^2.4.2" },"dependencies": { "@angular/core": "^4.3.3","@angular/http": "^4.3.3","amazon-cognito-identity-js": "^1.19.0","rxjs": "^5.4.2" } }
编译包后,我链接包
npm link
npm link @myapp/services
然后我将服务模块导入到我的主app模块中
@NgModule({ declarations: [ MyApp ],imports: [ BrowserModule,IonicModule.forRoot(MyApp),MyAppServicesModule,LoginPageModule,DocumentsPageModule,],bootstrap: [IonicApp],entryComponents: [ MyApp ],providers: [ StatusBar,SplashScreen,{provide: ErrorHandler,useClass: IonicErrorHandler} ] }) export class AppModule {}
在我的登录页面中,我导入AuthenticationService并在构造函数中声明它,以便它由依赖注入器设置
import { AuthenticationService } from '@myapp/services' @IonicPage() @Component({ selector: 'page-login',templateUrl: 'login.html',}) export class LoginPage { constructor (public navCtrl: NavController,public navParams: NavParams,public authenticationService: AuthenticationService) {}
但是在尝试提供我的应用程序时出现以下错误
typescript: src/pages/login/login.ts,line: 27 Cannot find name 'AuthenticationService'. L26: public navParams: NavParams,L27: public authenticationService: AuthenticationService) {}
对于来自服务模块的任何提供程序的所有引用,我也会收到相同的错误.我已经尝试在服务模块的exports部分列出服务,但是没有解决问题.
我的离子版
Ionic Framework: 3.2.1 Ionic App Scripts: 1.3.7 Angular Core: 4.1.0 Angular Compiler CLI: 4.1.0 Node: 7.7.1 OS Platform: macOS Sierra Navigator Platform: MacIntel User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/603.2.4 (KHTML,like Gecko) Version/10.1.1 Safari/603.2.4
谢谢
