构建错误：存在两个具有此名称的不同类型，但它们不相关

Question

构建我的JHipster Angular项目时出现此错误

[ERROR] Error at /Users/Dan/work/gba/node_modules/ng-jhipster/src/interceptor/interceptable-http.d.ts:4:22: Class 'InterceptableHttp' incorrectly extends base class 'Http'.
[ERROR]   Types of property 'request' are incompatible.
[ERROR]     Type '(url: string | Request, options?: RequestOptionsArgs) => Observable<Response>' is not assignable to type '(url: string | Request, options?: RequestOptionsArgs) => Observable<Response>'. Two different types with this name exist, but they are unrelated.
[ERROR]       Type 'Observable<Response>' is not assignable to type 'Observable<Response>'. Two different types with this name exist, but they are unrelated.
[ERROR]         Property 'source' is protected but type 'Observable<T>' is not a class derived from 'Observable<T>'.
