Thanks in Advance.

回答1:

md prefix was announced as deprecated in 2.0.0-beta.11 and seems now(2.0.0-beta.12) it is removed. We should use mat instead.

So instead of importing:

MdTabsModule

and

<md-tab-group class="demo-tab-group">
  <md-tab label="Tab 1">

use

MatTabsModule

and

<mat-tab-group class="demo-tab-group">
  <mat-tab label="Tab 1">

Plunker Example@2.0.0-beta.12

Or you can set angular-material version to @2.0.0-beta.11 explicitly:

'@angular/material': 'https://unpkg.com/@angular/material@2.0.0-beta.11/bundles/material.umd.js',

Plunker

I also advice you to see all examples here
