Babylon Syntaxfehler mit reagieren nativ

Question

Ich bekomme diesen kryptischen Fehler in React Native. Versucht, meine Pakete mit npm neu zu installieren und meine eigene Codesyntax zu überprüfen, aber ohne Fortschritt.

Das Konsolenprotokoll bezieht sich nur auf diese Datei: node_modules/babylon/lib/index.js

Was ist die wahrscheinliche Ursache und wie mehr Debug-Informationen über diesen Fehler zu bekommen?

Answer 1

Das Problem war mit dem render() Verfahren eines der Reaktion Mutter Komponenten und die Verwendung eines Spread-Operator an der falschen Stelle,

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

musste

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

geändert werden
