javascript - 急速模块命名冲突 : react native app with AWS Service (Amplify Project)

Question

我已经开始使用 react native 项目，之前是在本地代码中。
我想添加 Amazon Lex，所以按照链接中的以下步骤操作

https://aws-amplify.github.io/docs/js/interactions

下面是我的 App.js 文件

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';

export default function App() {
  return (
    <View style={styles.container}>
      <Text>Open up App.js to start working on your app!</Text>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

我刚刚设置了放大库并为 LEX 添加了交互，但是当我尝试运行应用程序时开始出现错误。在添加之前工作正常......一旦创建了 Amplify 文件夹并开始出现后端错误......

我已将所有最新版本用于 react-native。

我尝试了以下解决方案但无法正常工作 how to make react native packager ignore certain directories

我只是按照步骤......我哪里出错了......错过了任何东西......
请帮助......这是我第一个 react 原生的应用程序......我实际上迷路了

Answer 1

经过许多不眠之夜和测试不同的解决方案，我终于能够通过..我使用最新的 react-native > 0.59(我猜是 0.61)
我的应用程序已经在根目录创建了 metro.config.js 文件，必须编辑相同的文件。

const blacklist = require('metro-config/src/defaults/blacklist');   // on top

resolver: {
    blacklistRE: blacklist([/#current-cloud-backend\/.*/])         //add within module export  
  }

我呼吸了新鲜空气……现在一切正常……

请不要创建新的 metro.config.js 或 rn-cli.config.js。使用 编辑当前的 metro.config.js #current-cloud-backend 不是 后台文件夹。这个非常重要。
后端将被忽略....

这将对将来的某人有所帮助....因为给出的解决方案都不起作用....对于最新的 native react 。
