這篇文章主要給大家介紹了關于Angular5升級RxJS到5.5.3報錯：EmptyError: no elements in sequence的解決方法，文中介紹了兩個解決方法，大家可以選擇使用，需要的朋友可以參考借鑒，下面來一起看看吧。

前言

RxJS是一種針對異步數(shù)據(jù)流編程工具，或者叫響應式擴展編程；可不管如何解釋RxJS其目標就是異步編程，Angular引入RxJS為了就是讓異步可控、更簡單?？墒亲罱谏壷杏龅搅艘恍﹩栴}，下面就來給大家介紹下，給同樣遇到這個問題發(fā)朋友們一些參考，下面話不多說了，來一起看看詳細的介紹吧。

Angular 5.0.5升級RxJS到5.5.3報錯：

ERROR Error: Uncaught (in promise): EmptyError: no elements in sequence
EmptyError: no elements in sequence
 at new EmptyError (EmptyError.js:28)
 at FirstSubscriber._complete (first.js:154)
 at FirstSubscriber.Subscriber.complete (Subscriber.js:122)
 at MergeMapSubscriber._complete (mergeMap.js:150)
 at MergeMapSubscriber.Subscriber.complete (Subscriber.js:122)
 at MapSubscriber.Subscriber._complete (Subscriber.js:140)
 at MapSubscriber.Subscriber.complete (Subscriber.js:122)
 at EmptyObservable._subscribe (EmptyObservable.js:83)
 at EmptyObservable.Observable._trySubscribe (Observable.js:172)
 at EmptyObservable.Observable.subscribe (Observable.js:160)
 at new EmptyError (EmptyError.js:28)
 at FirstSubscriber._complete (first.js:154)
 at FirstSubscriber.Subscriber.complete (Subscriber.js:122)
 at MergeMapSubscriber._complete (mergeMap.js:150)
 at MergeMapSubscriber.Subscriber.complete (Subscriber.js:122)
 at MapSubscriber.Subscriber._complete (Subscriber.js:140)
 at MapSubscriber.Subscriber.complete (Subscriber.js:122)
 at EmptyObservable._subscribe (EmptyObservable.js:83)
 at EmptyObservable.Observable._trySubscribe (Observable.js:172)
 at EmptyObservable.Observable.subscribe (Observable.js:160)
 at resolvePromise (zone.js:824)

這應該是RxJS升級導致的，參考issue。

方法一

在所有的route里加上pathMath:"full"，如

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

改為

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

方法二

RxJS降為版本5.5.2。

注意：降版本時一定要把之前的卸載掉。
