Question

我已经安装：

npm install --save @angular/material @angular/cdk @angular/animations

，并尝试将MatTableDataSource简单地导入到我的组件中，而不使用它：

import {MatTableDataSource} from "@angular/material";

我已经收到以下错误：

ERROR in node_modules/@angular/cdk/a11y/typings/focus-monitor/focus-monitor.d.ts(79,22): error TS2315: Type 'ElementRef' is not generic.

Answer 1

从上面的package.json文件中，您似乎正在使用角度5和角度7 /材质7，这会给您带来麻烦。

将 @angular/material 软件包降级到匹配的版本（或尝试将angular升级到7版本

Answer 2

我也遇到了同样的问题，我在角上安装了相同版本的材料

npm install --save @angular/material@5.2.5 @angular/cdk@5.2.5

从“ @ angular / material”导入“ MatTableDataSource”时出错
