NodeInvocationException：由于错误而导致预呈现失败：错误：找不到模块“ @ angular / common / http”

Question

我使用Visual Studio创建了一个新项目，并将其从angular4升级到angular6。升级后，我面临”错误：找不到模块“ @ angular / common / http”“

尝试导入 httpclientmodule 但没有运气

    ];

    ngOnInit() {
      // this.userService.getApiList().subscribe(data => { console.log(data); this.ArrApiLi = data; });

    }



}

每当我运行该应用程序时，它将显示错误。 HTTPModule已经声明并导入。

需要帮助！！！
