解析www/config.xml時出錯：TypeError：無法讀取未定義的屬性'0'

Question

你知道我該如何解決這個問題嗎？我是Ionic的新手。對於參考，我使用Ionic Market Place的version 1 of this app。

Answer 1

在WWW文件夾中刪除config.xml的問題解決了：

Monas-MacBook-Pro:social_network mona$ cd www 
Monas-MacBook-Pro:www mona$ ls 
config  css  img  index.html js  lib  templates 

也提到here，顯然這是一個PhoneGap的建設問題。
