javascript - React Native "TypeError: Object(...) is not a function" react 导航堆栈错误

Question

我的 react 导航堆栈有问题，我相信这可能是依赖项的问题，但我不确定是否就是这样。我只是想将一些文本重定向到另一个页面。如果有与问题无关的代码，例如按钮，我很抱歉，因为我正在尝试学习 native react 。问题是在第一次导入时指向 homeStack.js，“import { createStackNavigator } from '@react-navigation/stack';” ，但之前我只是在那里使用了react-navigation-stack，我相信这是旧依赖项的一部分，但它一开始给了我一个模块未找到的错误，当我放置@react-navigation/时，它变成了我现在所拥有的堆栈代替。我正在学习视频教程，但教程中的代码无法编译。我多次重新下载 react 导航并尝试了一些不起作用的东西。我将在下面发布我的代码，并且非常感谢帮助和输入什么可以帮助我的问题。感谢您!

homeStack.js

import { createStackNavigator } from '@react-navigation/stack';
//import { createAppContainer } from '@react-navigation/native';
//import { createStackNavigator } from 'react-navigation-stack';
import { createAppContainer } from 'react-navigation';
import Home from '../screens/home';
import ReviewDetails from '../screens/reviewDetails';

const screens = {
Home: {
screen: Home,
},
ReviewDetails: {
screen: ReviewDetails,
},
};

// home stack navigator screens
const HomeStack = createStackNavigator(screens);

export default createAppContainer(HomeStack);

home.js

import React from 'react';
import { StyleSheet, View, Text, } from 'react-native';
import { globalStyles } from '../styles/global';

export default function Home() {
  return (
    <View style={globalStyles.container}>
       <Text style={globalStyles.titleText}>Home Screen</Text>
    </View>
  );
}

App.js

//import React from 'react';
import React, { Component } from 'react';
import { StyleSheet, Text, View, Image, Button } from 'react-native';

//export default function App() {
export default class App extends Component {

    this.props.navigation.navigate("Screen");
  //    this.navigation.navigate("screen2");

   editUser2 = () => {
  //if the second button is clicked, it will redirect to yahoo.com
        window.location.href="http://yahoo.com"

      <Button

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    alignItems: 'center',
    justifyContent: 'center',
  },
  title: {
    fontSize: 32,

    margin: 10,
  },

错误表明出了什么问题 -

Object(...) is not a function

createStackNavigator 需要一个函数，并且您将一个对象作为参数传递给它。根据docs

你的代码应该是这样的 -

import { createStackNavigator } from '@react-navigation/stack';
//import { createAppContainer } from '@react-navigation/native';
//import { createStackNavigator } from 'react-navigation-stack';
import { createAppContainer } from 'react-navigation';
import Home from '../screens/home';
import ReviewDetails from '../screens/reviewDetails';

const Stack = createStackNavigator();

function MyStack() {
  return (
    <Stack.Navigator>
      <Stack.Screen name="Home" component={Home} />
      <Stack.Screen name="ReviewDetails" component={ReviewDetails} />
    </Stack.Navigator>
  );
}

export default MyStack; //you need to render this

现在在你的根文件中，它应该是这样的(不包括你的附加代码)-

import { createStackNavigator } from '@react-navigation/stack';
import MyStack from "yourPath";

export default function App() {
  return (
    <NavigationContainer>
      <MyStack />
    </NavigationContainer>
  );
}
