按照https://angular-update-guide.firebaseapp.com/中描述的步骤将我的 angular 4 应用程序升级到 5

我已经使用 @latest 安装了所有最新的软件包，而不是上面链接中提到的特定版本。

ng serve --open 失败并出现以下错误

错误 TS2688 中的错误：找不到“flex-layout”的类型定义文件。

我在@angular/flex-layout/ 看到了一个文件 flex-layout.d.ts

下面是我的 package.json 文件

你flexLayoutModule在你的导入了app.module.ts吗？如果没有，请使用以下行导入它：

import {FlexLayoutModule} from '@angular/flex-layout';

此外，包括FlexLayoutModule在app.module.ts文件的导入数组中。
