您好我有一个登录组件,其中包含指向注册组件的链接。
当我单击此链接时,我遇到了这个问题:
ERROR Error: Uncaught (in promise): Error: No provider for HttpClient!
Error: No provider for HttpClient!
at injectionError (core.es5.js:1169)
at noProviderError (core.es5.js:1207)
at ReflectiveInjector_.webpackJsonp.../../../core/@angular/core.es5.js.ReflectiveInjector_._throwOrNull (core.es5.js:2649)
at ReflectiveInjector_.webpackJsonp.../../../core/@angular/co...
登录组件加载良好,注册失败。
在登录组件 html 上,我有:
<a [routerLink]="['/register']" class="btn btn-link">Register</a>
我的应用程序路由如下所示:
const appRoutes: Routes = [
{ path: '', component: HomeComponent, canActivate: [GuardService] },
{ path: 'login', component: LoginComponent },
{ path: 'register', component: RegisterComponent },
// otherwise redirect to home
{ path: '**', redirectTo: '' }
];
export const routing = RouterModule.forRoot(appRoutes);
我正在使用的版本:Node.js 版本:v8.5.0 NPM 版本:5.4.2
谢谢!
