vue-router TypeError: Cannot read property ‘$createElement‘ of undefined

路由不跳转，还报错，router 文件夹下的 index.js 代码如下：

错误的原因是把 component 写成了 components

import manage from '../views/manage/manage.vue'
import testManage from "../views/manage/StudentManage/testManage";const routes = [{
    path: '/',name: 'manage',component: manage,children: [{
    path:'testManage',components:testManage}]},{
    path: '*',name: 'manage',component: manage}
]
export default routes
