我的初始屏幕不会移动到 react 本机上的下一个屏幕

Question

我是React Native的新手，我正在尝试创建一个iOS应用程序。我的Splash屏幕正常工作，并在创建Project Fim时加载初始app.js屏幕。但是，当我将返回到自己的.js文件时，它将无法构建，并且被卡在Splash屏幕上。请给我一些提示，我遵循了许多教程。

app.js

// App.js
import React, { Component } from 'react';
import SplashScreen from 'react-native-splash-screen';
import GetStarted from './authentication/GetStarted'
import { createStackNavigator, createAppContainer } from 'react-navigation'
const AuthNav = createAppContainer(
  createStackNavigator({
    GetStarted: { screen: GetStarted },
  })
);
type Props = {};
export default class App extends Component<Props> {
  componentDidMount() {
    SplashScreen.hide()
  }
  render() {
    return (
      <AuthNav />
    );
  }
}

getstarted.js

//GetStarted.js
import React, { Component } from 'react';
import {
  View,
  Text,
  StyleSheet,
} from 'react-native';
export default class GetStarted extends Component {
  render() {
    return (
      <View style={styles.container}>
        <Text>Lets get started</Text>
      </View>
    );
  }
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItem: 'center',
    justifyContent: 'center',
    backgroundColor: 'blue'
  }
});

package.json

{
"name": "TestApp",
"version": "0.0.1",
"private": true,
"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"

}

Answer 1

您正在使用"react-navigation": "^3.3.0"并尝试导入StackNavigator。在v2+中，他们将StackNavigator重命名为createStackNavigator。看起来您使用的教程是使用v1。因此，您可以将使用的版本更改为"react-navigation": "^1.5.2"，也可以使用createStackNavigator。如果您选择坚持使用的版本（v2+），请在此处阅读我对同一问题的另一个回答；它将进一步解释。
