Question

我一直收到这个错误。我尝试了多个不同的 node.js 版本（12、13、14），但仍然出现错误。我也尝试过使用 val 而不是 import ，但没有用。

这是我的代码：

import {createAppContainer } from 'react-navigation'
import {createStackNavigator } from 'react-navigation-stack'
import SearchScreen from './src/screens/SearchScreen'
    
const navigator = createStackNavigator({
        Search: SearchScreen
    },
    {
        initialRouteName: 'Search',
        defaultNavigationOptions: {
        title: 'Business Search'
    }
})
    
export default createAppContainer(navigator)

这里是错误：

/Users/macbook/Downloads/food-boilerplate/node_modules/react-navigation/src/index.js:1
export * from '@react-navigation/core';
^^^^^^

SyntaxError: Unexpected token 'export'

非常感谢任何帮助 - 我已经尝试解决这个问题超过 5 个小时了。

谢谢:)

这是我对 React Navigation 的导入：

import { NavigationContainer } from "@react-navigation/native";
import { createStackNavigator } from "@react-navigation/stack";

我正在使用官方文档中提供的那些。我不知道这是否有什么不同，但请看一看。

不断收到“SyntaxError: Unexpected token 'export'” - 我该怎么办/出了什么问题？
