推荐答案

MaterialModule在版本 2.0.0-beta.3 中已弃用，并且在版本 2.0.0中已完全删除. -beta.11 .有关更多详细信息，请参见此 CHANGELOG .请经历重大变化.

MaterialModule depreciated in version 2.0.0-beta.3 and it was removed completely in version 2.0.0-beta.11. See this CHANGELOG for more details. Please go through the breaking changes.

MaterialModule已被删除，不再可用.如前所述 在beta.3的变更日志中，是一个汇总模块，例如MaterialModule 防止工具能够树状摇晃未使用的组件，并且 模块.

MaterialModule has been removed and is no longer available. As noted in the changelog for beta.3, an aggregate module like MaterialModule prevents tools from being able to treeshake unused components and modules.

此外，使用2.0.0-beta.11和更高版本，将您的角度版本更新为4.4.3或更高版本.材料2.0.0-beta.11取决于4.4.3或更大.赞一下CHANGELOG:

Also, with 2.0.0-beta.11 and greater, update your angular version to 4.4.3 or greater. Material 2.0.0-beta.11 depends on 4.4.3 or greater. Feom the CHANGELOG:

重大更改 Angular Material现在需要Angular 4.4.3或更高版本

Breaking changes Angular Material now requires Angular 4.4.3 or greater

现在您有两个选择:

1. 降级到2.0.0-beta.10
2. 包括单独的材料组件模块，以便在您的应用中使用它们.

第二种情况下

import { MatSelectModule, MatButtonModule } from '@angular/material';

...
imports: [ 
    ....
    MatSelectModule,
    ‎MatButtonModule
]

最后，请记住，由于已删除2.0.0-beta.12 Md前缀，因此您应在所有位置使用Mat前缀.在2.0.0-beta.11的CHANGELOG中:

Lastly, remeber that since 2.0.0-beta.12 the Md prefix has been removed and you should use Mat prefix everywhere. From the CHANGELOG of 2.0.0-beta.11:

对于beta.11，我们已决定弃用"md"前缀 完全使用垫子"向前移动.这会影响所有的类名， 属性，输入，输出和选择器(更改了CSS类 早在二月).下一个Beta中将删除"md"前缀 释放.

For beta.11, we've made the decision to deprecate the "md" prefix completely and use "mat" moving forward. This affects all class names, properties, inputs, outputs, and selectors (CSS classes were changed back in February). The "md" prefixes will be removed in the next beta release.

并且来自2.0.0-beta.12的CHANGELOG:

And from the CHANGELOG of 2.0.0-beta.12:

重大更改 所有"md"前缀均已删除.

Breaking Changes All "md" prefixes have been removed.
