WebStorm-参数类型{providedIn:"root"}不可分配给参数类型{providedIn:Type< any>. | “根" | null}&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

我正在尝试将应用程序从Angular v5迁移到v6，并且在尝试在提供程序中指定providedIn时遇到以下打字错误:

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

不可将参数类型{providedIn:"root"}分配给参数类型{providedIn:Type | 根" | null}& InjectableProvider

Argument type {providedIn: "root"} is not assignable to parameter type {providedIn: Type | "root" | null} & InjectableProvider

 @Injectable({
    providedIn: 'root',
 })
 export class MyService {
 }

我复制并粘贴了Angular文档中的代码 https://angular.io/guide/dependency-注射

I copied and pasted the code from the Angular doc https://angular.io/guide/dependency-injection

有什么主意吗?

更新

我创建了一个空白项目ng new ...，并添加了一个提供程序ng g service my-new-service，在WebStorm中打开了该项目，一切正常，我没有遇到任何与该虚拟项目有关的错误

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
