反応ネイティブのBabylon構文エラー

Question

React Nativeにこのような見た目の誤りがあります。私のパッケージをnpmで再インストールし、自分のコード構文をチェックしてみましたが、進歩はありませんでした。

コンソールログにのみ、このファイルを参照： node_modules/babylon/lib/index.js

何原因である可能性があり、どのようにこのエラーの詳細デバッグ情報を取得しますか？

Answer 1

問題が反応ネイティブ構成要素のうちの1つのrender()方法と間違った場所にスプレッド演算子を使用していた、

render(){ 
    return (
     <View> 
     {...this.props.children} 
     </View> 
    ) 
    } 

は

render(){ 
    return (
     <View> 
     {this.props.children} 
     </View> 
    ) 
    } 

に変更する必要がありました
