Question

我正在尝试在Angular 6项目上设置Angular Material。但是，尝试运行时：

ng generate @angular/material:material-nav --project=ui-project

我收到以下错误消息：

Cannot read property 'replace' of undefined

这是我的package.json

  }
}

我正在运行以下内容：角CLI：6.2.1 节点：10.9.0 操作系统：Darwin x64 角度：6.1.7

几周后，并重做了整个有角度的项目对象，我最终不得不将cli升级到版本7。使用ng update -all命令将所有依赖关系更新到正确的版本，这样就可以正常工作。

这是结果

Package                      Version
------------------------------------------------------
@angular-devkit/architect    0.10.2
@angular-devkit/core         7.0.2
@angular-devkit/schematics   7.0.2
@schematics/angular          7.0.2
@schematics/update           0.10.2
rxjs                         6.3.3
typescript                   3.1.3

无法运行ng generate @ angular / material：material-nav
