vue中的router，路径显示正确但是内容却不能显示，查不到问题出在哪里？

Question

使用 <router-view></router-view>
路径显示正确但是内容却不能显示，也不报错，不知道是哪里的问题？

路由改成这样：

menus.forEach(item => {
  var childArr = item.childs;
  childArr.forEach(sub => {
    routes.push({
      path: `@/demos/${sub.entity.componentName}`,
      name: sub.entity.name,
      component: () => import(`@/demos/${sub.entity.componentName}`)
    })
    console.log('aaa' + sub.entity.componentName)
  })
});

现在不知道哪里的问题，无从下手。
这是菜单：

module.exports = [
        {
            "entity": {
                "id": 1,
                "parentMenuId": 0,
                "name": "systemManage",
                "componentName": "SystemManage",
                "alias": "系统管理",
                "state": "ENABLE",
                "sort": 0,
                "value": null,
                "type": "NONE",
                "discription": "用于系统管理的菜单",
                "createUserId": 1
            },
            "childs": [
                {
                    "entity": {
                        "id": 3,
                        "parentMenuId": 1,
                        "name": "authManage",
                        "componentName": "AuthManage",
                        "icon": "el-icon-loading",
                        "alias": "权限管理",
                        "state": "ENABLE",
                        "sort": 0,
                        "value": "/system/auth",
                        "type": "LINK",
                        "discription": "用于权限管理的菜单",
                        "createUserId": 1
                    },
                    "childs": null
                },
                {
                    "entity": {
                        "id": 4,
                        "parentMenuId": 1,
                        "name": "roleManage",
                        "componentName": "RoleManage",
                        "icon": "el-icon-bell",
                        "alias": "角色管理",
                        "state": "ENABLE",
                        "sort": 1,
                        "value": "/system/role",
                        "type": "LINK",
                        "discription": "用于角色管理的菜单",
                        "createUserId": 1
                    }
                  }
                }
            ]
        }
    ]

如图中圈起的重点，你访问的路由地址应该是/system/auth才对
