问题描述
我正在尝试使用 Angular Material Table 创建一个表例子中总是有导入:
I'm trying to create a table using Angular Material Table, in the examples there is always the import:
import {MatTableDataSource} from '@angular/material';
我正在尝试执行相同的操作，但出现错误:模块' ../node_modules/@ angular/material/material '没有导出的成员 MatTableDataSource .
I'm trying to do the same but I'm getting an error: "Module '../node_modules/@angular/material/material' has no exported member MatTableDataSource.
有什么我想念的吗?
这是package.json版本:
Here's the package.json versions:

推荐答案
我遇到了同样的问题.事实证明，MatTableDataSource是Angular Material 5.0.0-rc0中的新功能.我将角度4更新为角度5，并将角度材质更新为5.0.0-rc0. (参考: https://github.com/angular/material2/releases )
I was having the same problem. Turns out, MatTableDataSource is new feature in Angular Material 5.0.0-rc0.I updated angular 4 to angular 5 and updated angular material to 5.0.0-rc0. (ref: https://github.com/angular/material2/releases)
如果有帮助，这是我的package.json文件.
