所以,我对 vue.js 还是很陌生,这很可能是我犯的愚蠢错误,但是可惜,Google 今天似乎不是我的朋友,因为我已经搜索了 2 个多小时并发现没有什么。
尝试加载组件时出现我的问题。该组件嵌套在其他组件中,路由器应该加载它。我有其他以这种方式加载的组件(使用<router-view></router-view>
和路由器)没有任何问题。这个组件唯一不同的是它在它的根下嵌套了 3 层,而在我的所有其他组件中,我走的最深的是 2 层。
当我尝试加载此组件时,我收到 2 个警告和一个错误:
警告 1:
[vue-router] Failed to resolve async component render: TypeError: Cannot read property '$createElement' of undefined
警告 2:
[vue-router] uncaught error during route navigation
错误:
TypeError: Cannot read property '$createElement' of undefined

我的路由看起来像这样;我的两个beforeEnter
钩子都在应该调用的时候被调用,无法加载的组件是smsConfigDetails
:
import allConfigs from 'pages/config-pages/allConfigs'
import smsConfigs from 'pages/config-pages/sms/allSmsConfigs'
import smsDetails from 'pages/config-pages/sms/smsConfigDetails'
export default [
{
path: '/',
component: () => import('layouts/default'),
children: [
{ path: '', component: () => import('pages/index') },
[...]
{
path: 'allconfigs',
component: allConfigs,
children: [
{
path: 'sms',
component: smsConfigs,
children: [
{
path: ':configId',
components: smsDetails,
beforeEnter: (to, from, next) => {
console.log('SMS Details beforeEnter()')
next()
}
}
],
beforeEnter: (to, from, next) => {
console.log('SMS list beforeEnter()')
next()
}
}
]
}
[...]
]
},
{ // Always leave this as last one
path: '*',
component: () => import('pages/404')
}
]
加载失败的组件代码现在非常简单:
<template>
<div>
blablabla
</div>
</template>
<script>
</script>
<style>
</style>
父母只有一个<router-view></router-view>
