不知道这个对路由的配置有什么要求

### Description
1.我的路由配置大概是这样的，有个组件mobileLayout专门写了一些移动端的样式，作为嵌套路由
移动端都在这个组件里
```javascript
{
path: '',
component: mobileLayout,
children: [
{
path: 'index',
name: '列表页',
component: () =>
import ('@/views/home/index'),
meta: {
title: '大视VLOG',
icon: ''
},
},
{
path: 'download',
name: '下载页',
component: () =>
import ('@/views/download/index'),
meta: {
title: '大视VLOG',
icon: ''
},
},
{
path: 'play',
name: '视频详情',
meta: {
title: '大视VLOG'
},
props: (route) => ({
query: route.query.videoId
}),
component: () =>
import ('@/views/play/index')
},
{
path: 'userCenter',
name: '个人主页',
meta: {
title: '大视VLOG'
},
props: (route) => ({
query: route.query.userId
}),
component: () =>
import ('@/views/userCenter/index')
}
]
}
```
什么也生成不出来，看了弹出的页面控制台报错了

2.如果我只配置很简单的路由，就可以生成了，但生成的骨架元素尺寸很有问题，并且高度填不满页面。
```javascript
{
path: '',
name: 'root',
component: mobileLayout,
children: [{
path: 'index',
name: '列表页',
component: () =>
import ('@/views/home/index'),
meta: {
title: '大视VLOG',
icon: ''
},
}]
}
```
请见图

谢谢

### Plugin configration

for example:

```javascript
new SkeletonPlugin({
pathname: path.resolve(__dirname, './shell'), // the path to store shell file
staticDir: path.resolve(__dirname, './dist'), // the same as the `output.path`
routes: ['/', '/index','/play','/userCenter'], // Which routes you want to generate skeleton screen
defer:20000,
device:'iPhone X'
}),
```

### Versions

- Page Skeleton:0.10.12
- Webpack:3.6.0

Start by reproducing the two configurations in the issue with Page Skeleton 0.10.12 and Webpack 3.6.0, using the listed routes, device, and output paths. Inspect the linked console-error and sizing screenshots, then determine why the nested routes fail and why the generated skeleton dimensions do not fill the page; done means both configurations generate correctly sized output.
