Question

我删除我的src文件夹后,为了重构这个错误发生.我相信这是一个缓存问题？我试着遵循这个要点,但没有运气.

"反应":"16.4.1",

"反应原生":"0.56.1",

"@ babel/core":"^ 7.1.2",

import React, { Component } from 'react';
import { Platform, Text, View } from 'react-native';
import { Provider } from 'react-redux';
import { store } from './src/redux/store';


export default class App extends Component<Props> {
    state = {
        isLoadingComplete: false,
    };

    render() {
        return (

            <View>
                <Text>Hello??</Text>
                <Text>Hello??</Text>
                <Text>Hello??</Text>
                <Text>Hello??</Text>
                <Text>Hello??</Text>
                <Text>Hello??</Text>
                <Text>Hello??</Text>
            </View>
        );
    }
}
