通过使用ng2-translation软件包,在angular2中使转换动态化
我得到的错误如下：未处理的承诺拒绝：没有TranslateService的提供商！

解决方法
我知道这个问题现在已经很老了,但是对于任何人来到这个页面寻找同样的问题,请仔细检查你是否在@NgModule providers数组中添加了服务.
在我的情况下,我想在一个模块中导入一个自定义服务’AuthGuard’,并不断收到错误’未处理的承诺拒绝：没有AuthGuard服务提供商’.我对这个问题的解决方法是 –
@NgModule({
declarations: [
TicketListComponent,TicketDetailComponent
],imports: [
CommonModule,RouterModule.forChild(appRoutes)
],providers: [
AuthGuard
]
})
