Question

将materialModule（已弃用的）更改为customMaterialModule（根据此url：https://material.angular.io/guide/getting-started）后，我不得不更新我的package.json（我做了npm update --save）。然后我在下面的错误。（我已经在github材料问题https://github.com/angular/material2/issues/7377上打开了这个问题，但没有好的答案）

Answer 1

您正在导入带有Mat前缀的材料模块，因此您必须在模板amd打字稿代码中使用mat前缀。更改以下内容：

<md-menu #menuCart="mdMenu" >

为：

<mat-menu #menuCart="matMenu" >

..以及md的所有其他mat前缀。

请参阅此答案示例： https://stackoverflow.com/a/46469671/1791913

请参阅此stackblitz demo中的用法。

材料角度CLI问题。没有指令＆＃34; exportAs＆＃34;设置为＆＃34; mdMenu＆＃34;
