路由报错Error in render: "TypeError: Cannot read properties of undefined

路由报错"Error in render: TypeError: Cannot read properties of undefined (reading 'matched')"是在Vue.js中在路由部分常见的报错。该报错导致页面无法正常显示。

其中，报错信息中的"TypeError: Cannot read properties of undefined (reading 'matched')"表示尝试读取未定义属性'matched'，导致了报错。

根据提供的代码片段，可以看出原始的挂载Vue实例的写法存在问题。正确的写法应该是通过VueRouter实例来进行路由的挂载，而不是通过route选项。正确的示例代码如下：

new Vue({
  el: '#app',
  router, // 使用router选项来挂载VueRouter实例
  render: h => h(App),
})

在这个示例中，我们通过router选项将VueRouter实例router挂载到Vue实例上，从而实现了正确的路由配置。

需要注意的是，如果仍然出现类似的报错，可能是由于其他代码逻辑问题导致的。可以继续检查代码中是否存在未定义的属性或其他错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
