我的初始屏幕不会移动到下一个反应本机屏幕

Question

我是 React Native 的新手，我正在尝试创建一个 iOS 应用程序。我的初始屏幕工作正常，并在创建项目时加载初始 App.js 屏幕。但是，当我将 return 更改为我自己的 .js 文件时，它无法构建并卡在启动画面上。请给我一些提示，我遵循了很多教程。

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"
},
"dependencies": {
    "react": "16.6.3",
    "react-native": "0.58.3",
    "react-native-firebase": "^5.2.2",
    "react-native-navigation": "^2.12.0",
    "react-native-splash-screen": "3.0.6",
    "react-navigation": "^3.3.0"
},
"devDependencies": {
    "babel-core": "7.0.0-bridge.0",
    "babel-jest": "24.0.0",
    "jest": "24.0.0",
    "metro-react-native-babel-preset": "0.51.1",
    "react-test-renderer": "16.6.3"
},
"jest": {
    "preset": "react-native"
}
}

Answer 1

您正在使用 "react-navigation": "^3.3.0" 并试图导入 StackNavigator。在 v2+ 中，他们将 StackNavigator 重命名为 createStackNavigator。看起来您使用的教程正在使用 v1。因此，您可以将正在使用的版本更改为 "react-navigation": "^1.5.2" 或保留并使用 createStackNavigator。如果您选择坚持使用当前版本 (v2+)，请阅读我对同一问题的另一篇回复；它会进一步解释。
