Question

我正在使用Material UI Framework创建新的Angular 4应用程序。我按照给出的步骤进行了：https://material.angular.io/guide/getting-started。

但是当我正在'npm start'时，它无法编译并说： ERROR in /home/programoholic/workspace/heroapp/src/app/app.module.ts (3,10): Module '"/home/programoholic/workspace/heroapp/node_modules/@angular/material/material"' has no exported member 'MaterialModule'。

错误截图：

Answer 1

MaterialModule已在版本 2.0.0-beta.3 中折旧，并且已在 2.0.0-beta.11 版本中完全删除。有关详细信息，请参阅此CHANGELOG。请仔细检查一下这些变化。

MaterialModule已被删除，不再可用。如上所述在beta.3的更改日志中，像MaterialModule这样的聚合模块防止工具树木化未使用的组件和模块。

您需要包含单个材料组件模块才能在您的应用中使用它们。

Answer 2

导入Angular材质的各个模块，如下所示

import { matButtonModule,matCardModule,matMenuModule,matToolbarModule,matIconModule,matSelectModule } from '@angular/material';

无法在Angular 4中编译材料，给出：/ material“没有导出的成员'MaterialModule
