在执行ng build --prod时从角度4升级到角度5时出错

Question

错误：无法在client-src / app / shared / services / touch-systems.service.ts中解析TouchSystemsService的所有参数：（[object Object]，？，[object Object]）。< / p>

这是我的服务：

export class TouchSystemsService extends BehaviorSubject{
baseUrl: string ;

constructor(public http: HttpClient, private apiEndPoint: string, private 
configService: ConfigService) {
super(null);
this.baseUrl = '/api';

}
public fetchById(id: number, state?: State): Observable<any>
{
    if (!state) {
    let options = this.CreateHeaders();
    return this.http.get<any>(`${this.baseUrl}/${this.apiEndPoint}/${id}`, 
options);
}
const queryStr = `${toDataSourceRequestString(state)}`;
const hasGroups = state.group && state.group.length;
let options = this.CreateHeaders();

let result = this.http.get<any>(`${this.baseUrl}/${this.apiEndPoint}/${id}? 
${queryStr}`, options);
return result;
}

这是一项扩展上述服务的服务

export class SizeService extends TouchSystemsService {

dataResult: GridDataResult;

constructor(http: HttpClient, configService: ConfigService) {
super(http, 'size', configService);
}

public read(id:number): Observable<GridDataResult> {
return this.fetchById(id);
}

我正在使用角度版Angular：5.2.10
