属性＆＃x27;提升＆＃x27;在类型中无法分配给基本类型中的同一属性。

Question

我在 objection.d.ts 文件中遇到有关属性 lift 的错误，并且不确定如何纠正它。我正在使用RXJS版本5.0.1。

Error   TS2416  (TS) Property 'lift' in type 'Subject<T>' is not assignable to the same property in base type 'Observable<T>'.
  Type '<R>(operator: Operator<T, R>) => Observable<T>' is not assignable to type '<R>(operator: Operator<T, R>) => Observable<R>'.
    Type 'Observable<T>' is not assignable to type 'Observable<R>'.
      Type 'T' is not assignable to type 'R'.
        'R' could be instantiated with an arbitrary type which could be unrelated to 'T'.

/**
 * @class Subject<T>
 */
export declare class Subject<T> extends Observable<T> implements ISubscription {
    observers: Observer<T>[];
    closed: boolean;
    isStopped: boolean;
    hasError: boolean;
    thrownError: any;
    constructor();
    static create: Function;
    lift<R>(operator: Operator<T, R>): Observable<T>;
    next(value?: T): void;
    error(err: any): void;
    complete(): void;
    unsubscribe(): void;
    protected _subscribe(subscriber: Subscriber<T>): Subscription;
    asObservable(): Observable<T>;
}

Answer 1

RXJS打字中的签名不正确，并得到在v5.4.2中： https：//github.com/reactivex/ rxjs/pult/2722/files 。

因此，解决方案是为了更新为 代码>。
