单个的试过可以，但是2个就不行了，具体代码等如附件，请帮忙看下，谢谢！
若不支持就算了（代码基于你的项目代码），我也不再折腾这个。

一、\router\modules\role-list.js

import layout from ‘@/layout’

export default {
path: ‘/user’,
component: layout,
name: ‘roleList’,
meta: {
title: ‘user’,
icon: ‘personnel’
},
children: [
{
path: ‘/user/role’,
component: () => import(’@/views/role-list/zzz.vue’),
meta: {
title: ‘roleList’,
icon: ‘role’
},
children: [
{
path: ‘/TODO_111’,
component: () => import(’@/views/role-list/xxx.vue’),
meta: {
title: ‘test_3rd_1’,
icon: ‘xxx’
}
},
{
path: ‘/TODO_222’,
component: () => import(’@/views/role-list/zzz.vue’),
meta: {
title: ‘test_3rd_2’,
icon: ‘zzz’
}
}
]
}
]
}

二、\views\role-list\xxx.vue

三、\views\role-list\zzz.vue
