WebStorm - 参数类型 {providedIn: “root"} 不可分配给参数类型 {providedIn: Type<any>|“根"|空} &可注射提供者 [英] WebStorm - Argument type {providedIn: "root"} is not assignable to parameter type {providedIn: Type<any> | "root" | null} & InjectableProvider
问题描述
我正在尝试将我的应用程序从 Angular v5 迁移到 v6，并且在尝试在我的提供程序中指定 providedIn 时遇到以下打字稿错误
I'm trying to migrate my app from Angular v5 to v6 and I face the following typescript error while trying to specify providedIn in my providers
参数类型 {providedIn: "root"} 不能分配给参数类型 {providedIn: Type |根" |空} &InjectableProvider
Argument type {providedIn: "root"} is not assignable to parameter type {providedIn: Type | "root" | null} & InjectableProvider
@Injectable({
providedIn: 'root',
})
export class MyService {
}
我从 Angular 文档中复制并粘贴了代码 https://angular.io/guide/dependency-注射
I copied and pasted the code from the Angular doc https://angular.io/guide/dependency-injection
有什么想法吗?
更新
我创建了一个空白项目 ng new ... 并添加了一个提供者 ng g service my-new-service，在 WebStorm 中打开该项目，一切正常，我在那个虚拟项目中没有遇到任何错误
I have created a blank project ng new ... and added a provider ng g service my-new-service, opened the project in WebStorm and everything was ok, I didn't face any error with that dummy project
