Question

我已经将React Native与React Native Web项目结合在一起了，我想使用React Native元素，但是在向项目中添加React Native元素时出现错误。

./node_modules/react-native-elements/src/avatar/Avatar.js
SyntaxError: /home/hamidreza/Desktop/reactElement/node_modules/react-native-elements/src/avatar/Avatar.js: Unexpected token (72:4)

  70 | 
  71 |   const Utils = showAccessory && (
> 72 |     <TouchableHighlight
     |     ^
  73 |       style={StyleSheet.flatten([
  74 |         styles.accessory,
  75 |         {

我的web/webpack.config.js：

const path = require('path');
const webpack = require('webpack');

const appDirectory = path.resolve(__dirname, '../');
const babelLoaderConfiguration = {
  test: /\.js$/,
  include: [
    path.resolve(appDirectory, 'index.web.js'),
    path.resolve(appDirectory, 'src'),
    path.resolve(appDirectory, 'node_modules/react-native-uncompiled'),
    path.resolve(appDirectory, 'node_modules/react-native-vector-icons'),
    path.resolve(appDirectory, 'node_modules/react-native-elements'),
  ],
  use: {
    loader: 'babel-loader',
    options: {
      cacheDirectory: true,
      presets: ['react-native'],
      plugins: ['react-native-web'],
    },
  },
};

const imageLoaderConfiguration = {
  test: /\.(gif|jpe?g|png|svg)$/,
  use: {
    loader: 'url-loader',
    options: {
      name: '[name].[ext]',
    },
  },
};

module.exports = {
  entry: [path.resolve(appDirectory, 'index.web.js')],

  output: {
    filename: 'bundle.web.js',
    path: path.resolve(appDirectory, 'dist'),
  },
  module: {
    rules: [babelLoaderConfiguration, imageLoaderConfiguration],
  },

  resolve: {
    alias: {
      'react-native$': 'react-native-web',
    },
    extensions: ['.web.js', '.js'],
  },
};

我的package.json：

{
  "name": "ReactNativeWebApp",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "android": "react-native run-android",

    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我该如何解决这个问题？

Answer 1

由于“本机”软件包不包含编译后的代码（babel和jsx转换后的es5），因此要在网络中使用它们，必须将库添加到webpack配置中。

所以我必须将path.resolve(paths.appNodeModules, 'react-native-elements'),和path.resolve(paths.appNodeModules, 'react-native-rating'),添加到webpack，这样才能解决问题。
