我在React Native中有一个巨大的应用程序，目前我正致力于仅在Android上构建它。我必须升级react-native版本> = 0.59，以使其与适用于64位设备的新Google政策兼容，因为我无法再在Play商店上更新我的应用了。但是，我花了很多时间来更新现有应用程序中的react-native版本，但尝试了大约2天，但这很头疼，而且效果不理想。
现在我正在做的是，我创建了一个新的react-native应用程序，该应用程序基于最新的react-native版本0.60.4构建。我将所有代码从现有应用程序复制到了包括index.js的新应用程序中。但是在进行任何更改之前，代码可以正常工作，但是当我将以前的代码转移到新应用后，它便停止工作。我解决了大多数错误，但现在却出现如下错误：
TypeError: Object is not a function (near '...(0,S.default)...')
│
│ This error is located at:
│ in Te
│ in f
│ in RCTView
│ in RCTView
└ in c
我以前的代码是最新的并且可以正常工作。从上面的错误中，我无法确定实际问题在哪里以及什么。请在这里帮助我。
我的index.js：
const Navigation = () => StackNavigator(
{
SplashScreen: {screen : SplashScreen},
MapScreen:{screen:MapScreen},
// Login screens
SignUpScreen: {screen : SignUpScreen},
},
{
initialRouteName: 'SplashScreen',
transitionConfig,
headerMode: 'none',
navigationOptions: {
headerVisible: false
}
}
);
class MyApp extends React.Component {
render() {
console.log('this.props in MyApp SplashScreen', this.props); // This will list the initialProps.
return <Navigation screenProps={this.props} />;
}
}
AppRegistry.registerComponent(appName, () => MyApp);
我的initialRouteScreen是SplashScreen，如下所示：
