javascript - 它无法识别导入文件中的文件

Question

我创建了一个 MenuButton 以及其他 2 个页面，其中一个是设置屏幕，我在两个文件中导入了 MenuButton，它们似乎工作正常。但是当我在 DrawerNavigator 文件中导入设置 Screen 时，它无法识别 MenuButton

Failed to load bundle(http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false) with error:(Unable to resolve module `./Menu/MenuButton` from `/Users/camillebasbous/Project/Menu/SettingScreen.js`: The module `./Menu/MenuButton` could not be found from `/Users/camillebasbous/Project/Menu/SettingScreen.js`.

我已经尝试测试其他页面，经过几次测试后，我意识到这些页面中导入的 MenuButton 的存在导致了错误是否有办法导入已导入另一个要显示的文件或我是否必须在抽屉导航中导入它们，如果是的话如何构建代码。谢谢

抽屉导航代码:

import * as React from 'react';
import { Text, View, Image, ScrollView, StyleSheet } from 'react-native';
import {
  createDrawerNavigator,
  createAppContainer,
  DrawerItems,
  SafeAreaView,
} from 'react-navigation';
import SettingScreen from './Menu/SettingScreen'





class Home extends React.Component {
  static navigationOptions = {
    title: 'Home',

  };

  render() {
    return (
      <View style={styles.container}>

        <SettingScreen/>

      </View>
    );
  }
}



const Navigator = createDrawerNavigator(
  {
    Home,

  },
  {
    //drawerType: 'back',
    // drawerPosition: 'right',
    // drawerWidth: 200,
  drawerBackgroundColor: '#262A2C',
    // contentComponent: CustomDrawerContentComponent
  }
);

 export default createAppContainer(Navigator);

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    backgroundColor: '#ecf0f1',

  }
});

设置屏幕代码:

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import MenuButton from './Menu/MenuButton'

export default class SettingScreen extends React.Component{
    render(){
        return(
            <View style={styles.container}>
            <MenuButton/>
            <Text style={styles.text}>Settings</Text>
            </View>
        )
    }
}
const styles = StyleSheet.create({
    container: {
        flex: 1,
        backgroundColor: 'rgba(215,215,215,1)',
        alignItems: 'center',
        justifyContent: 'center',
    },
text:{
    fontSize: 30,
    }
});

菜单按钮代码:

import React from 'react';
import {AppRegistry, StyleSheet, View} from "react-native" ;
import Icon from 'react-native-vector-icons/Ionicons'
import {widthPercentageToDP as wp, heightPercentageToDP as hp} from 'react-native-responsive-screen'



export default class MenuButton extends React.Component {
    render() {
        return(

        <View >

        <Icon name= "ios-menu" size={wp('12%')} color='#9B9B9B' style={{position: 'absolute', top: wp('-82.5%'), left: wp('-46%'), }}></Icon>

                 </View>
        ) 
    }
}


AppRegistry.registerComponent('Menu', () => FixedDimensionsBasics);

您在导入时使用的路径是相对于您的文件的。因此，由于所有内容都位于同一文件夹中，因此您必须像这样更正导入路径:

1. 抽屉导航器代码

   import SettingScreen from './SettingScreen'
   

2. 设置屏幕代码

   import MenuButton from './MenuButton'
