这篇文章主要给大家介绍了关于Angular5升级RxJS到5.5.3报错EmptyError: no elements in sequence的解决方法，文中介绍了两个解决方法，大家可以选择使用，需要的朋友可以参考借鉴，狼蚁网站SEO优化来一起看看吧。

前言

RxJS是一种针对异步数据流编程工具，或者叫响应式扩展编程；可不管如何解释RxJS其目标就是异步编程，Angular引入RxJS为了就是让异步可控、更简单。可是最近在升级中遇到了一些问题，狼蚁网站SEO优化就来给大家介绍下，给同样遇到这个问题发朋友们一些参考，狼蚁网站SEO优化话不多说了，来一起看看详细的介绍吧。

Angular 5.0.5升级RxJS到5.5.3报错

这应该是RxJS升级导致的，参考。

方法一

在所有的route里加上pathMath:"full"，如

const routes: Routes = [
 { path: "", ponent: IndexComponent },
 { path: "home", ponent: HomeComponent },
 { path: "about", ponent: AboutComponent },
 ...
];

改为

const routes: Routes = [
 { pathMatch: 'full', path: "", ponent: IndexComponent },
 { pathMatch: 'full', path: "home", ponent: HomeComponent },
 { pathMatch: 'full', path: "about", ponent: AboutComponent },
 ...
];

方法二

RxJS降为版本5.5.2。

注意降版本时一定要把之前的卸载掉。
