【问题描述】：

-1) 按照官方说明生成发布APK。 a link

-2) 在下面运行此命令。

    $ cd android
    $ ./gradlew assembleRelease

-3) 结果：我收到以下错误消息。

错误：找不到模块'babel-preset-react-app'

我正在尝试使用 React Native 为 Android 应用创建发布版本。 我已经搜索了包括以下内容的潜在解决方案。但我还没有找到任何适合我的东西。 Module build failed (from ./node_modules/babel-loader/lib/index.js): Error: Cannot find module 'babel-preset-react'

[package.json] 第 9 到 41 行

[index.js]

import AppRegistry from 'react-native';
import App from './App';
import name as appName from './app.json';

[app.js]

import React, Component, PropTypes from 'react';
import  Platform, StyleSheet, Text, View, Image, Dimensions, Button, TouchableHighlight, WebView  from 'react-native';
import  createStackNavigator, createAppContainer, StackActions, NavigationActions, withNavigation  from "react-navigation";

预期结果：终端将完成本官方指南中描述的过程，并在此文件夹路径下生成一个 apk 文件 android/app/build/outputs/apk/release/app-release.apk

React Native 官方指南： https://facebook.github.io/react-native/docs/signed-apk-android

实际输出： 我收到以下错误消息。

index.js: 找不到模块 'babel-preset-react-app'

错误：找不到模块'babel-preset-react-app'

任何建议将不胜感激。

【参考方案1】：

我找到了解决方案。我会回答我自己的问题... 我从 package.json 中删除了以下行。 而且我现在不再看到此错误消息。

"plugins": [
  [
    "@babel/plugin-proposal-decorators",
    
      "legacy": true
    
  ]
]
