UNMET PEER DEPENDENCY @ ionic-native/core @ 3.4.4安裝無效angular2-virtual-scroll

Question

我開發了一個Ionic 2.3 Web應用程序，需要使用虛擬滾動條。

但是當我嘗試intall angular2虛擬滾動圖書館中，我得到這個錯誤：

corp-now@ E:\Projetos\Ionic2\CorpNow 
+-- UNMET PEER DEPENDENCY @ionic-native/core@3.4.4 invalid 
`-- angular2-virtual-scroll@0.1.5 

我怎麼能解決這個問題？

Answer 1

這似乎與離子2 /角2版中的問題。

通過使用Ionic 3來解決。

Answer 2

爲什麼你需要爲虛擬卷軸添加第三方模塊？這是離子的內置功能2.

Virtual Scroll displays a virtual, "infinite" list. An array of records is passed to the virtual scroll containing the data to create templates for. The template created for each record, referred to as a cell, can consist of items, headers, and footers.

For performance reasons, not every record in the list is rendered at once; instead a small subset of records (enough to fill the viewport) are rendered and reused as the user scrolls.

例子：

<ion-list [virtualScroll]="items"> 

    <ion-item *virtualItem="let item"> 
    {{ item }} 
    </ion-item> 

</ion-list>
