angular-material - ng 生成 @angular/material :material-nav --name=main-nav is not working

Question

我确实有角度 6，尽管 ng generate @angular/material:material-nav --name home不工作

得到类似的错误 Collection "@angular/material" cannot be resolved.
Error: Collection "@angular/material" cannot be resolved.

Answer 1

这是因为您还没有将@angular/material 添加到您的节点模块。先使用ng add @angular/material安装@angular/material，然后尝试生成组件
