自己的角度项目编译/刷新页面

Question

运行角度项目后几分钟，我运行ng serve角度cli编译项目并多次刷新页面，尽管代码没有更新/更改

角度cli中没有错误，只显示了多个编译日志

就我而言，我有一个未处理的 http 请求。一旦我添加了一个例外，问题就不再发生了。

  private handleError(error: HttpErrorResponse) {
    if (error.error instanceof ErrorEvent) {
      // A client-side or network error occurred. Handle it accordingly.
      console.error('An error occurred:', error.error.message);
    } else {
      // The backend returned an unsuccessful response code.
      // The response body may contain clues as to what went wrong.
      console.error(
        `Backend returned code ${error.status}, ` +
        `body was: ${error.error}`);
    }
    // Return an observable with a user-facing error message.
    return throwError(
      'Something bad happened; please try again later.');
  }

  // settings
  getSettings(): Observable<Settings> {
    return this.http.get<Settings>(`${this.localUrl}getSettings`)
      .pipe(map(response => response))
      .pipe(catchError(this.handleError))
  }
