在package.config中添加以下软件包

{
"@webpack-cli/init": "^0.2.2",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react-native": "2.1.0",
    "clean-webpack-plugin": "^3.0.0",
    "imports-loader": "^0.8.0",
    "json-loader": "^0.5.7",
 "react-native-webpack": "^0.1.1"
}


  "devDependencies": {
    "@babel/core": "^7.5.5",
    "@babel/preset-env": "^7.5.5",
    "@babel/preset-react": "^7.0.0",
    "@babel/runtime": "^7.5.5",
    "@react-native-community/eslint-config": "^0.0.5",
    "babel-cli": "^6.24.0",
    "babel-core": "^6.26.3",
    "babel-jest": "^24.9.0",
    "babel-loader": "^8.0.6",
    "babel-plugin-syntax-dynamic-import": "^6.18.0",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-stage-1": "^6.24.1",
    "css-loader": "^3.2.0",
    "eslint": "^6.2.2",
    "file-loader": "^4.2.0",
    "html-webpack-plugin": "^3.2.0",

    "mini-css-extract-plugin": "^0.8.0",

    "webpack-cli": "^3.3.7",
    "webpack-dev-server": "^3.8.0",
    "webpack-node-externals": "^1.7.2"
  }

我的Webpack.cnfig看起来像

const path = require('path');
const webpack = require('webpack');
const nodeExternals = require('webpack-node-externals');
var PACKAGE = require('./package.json');
var banner = PACKAGE.buildname + ' - ' + PACKAGE.version + ' | ' +
  '(c) ' + new Date().getFullYear() + ',  ' + PACKAGE.author + ' | ' + '\n' +  PACKAGE.license + ' \n' +
  PACKAGE.copyright;

const defaultConfig = {
    mode: "production",
    devtool: 'source-map',
    target: 'node', // in order too ignore built-in modules like path, fs, etc.
    externals: [nodeExternals()], // in order to ignore all modules in node_modules folde   
    module: {
        rules: [
            {
                test: /\.(js|jsx|mjs)$/,
                exclude: /node_modules/,
                 use: ['babel-loader']
            },
              {
                test: /\.(jpe?g|png|gif)$/i,
                exclude: /node_modules/,
                use: [
                  'file-loader?hash=sha512&digest=hex&name=[hash].[ext]',
                  'image-webpack-loader',
                ],
              },
              {
                test: /\.(sa|sc|c)ss$/,
                exclude: /node_modules/,
                use: [
                       {
                         loader: "css-loader",
                       },
                       {
                         loader: "postcss-loader"
                       },
                       {
                         loader: "sass-loader",
                         options: {
                           implementation: require("sass")
                         }
                       }
                     ]
            },
              {
                test: /\.(woff|woff2|ttf|otf|eot)$/,
                exclude: /node_modules/,
                use: [
                       {
                         loader: "file-loader",
                         options: {
                           outputPath: 'fonts'
                         }
                       }
                     ]
              }
        ]
    }
};
const reactNativeBundle = Object.assign({}, defaultConfig, { //Bundle 3: compile the react native client
    entry: {
        main: './Lw.Mobile.Base/App.js'
    },
    output: {
      filename: PACKAGE.buildname + ".js",
      library: PACKAGE.buildname,
      libraryTarget: "umd",
      path: path.join(__dirname, '/Bundled_modules'),
      sourceMapFilename: PACKAGE.buildname + ".js.map"
    },  
    resolve: {
      extensions: ['.js', '.jsx', '.json']
    },
    plugins: [
      new webpack.BannerPlugin(banner)
    ]
    
});

module.exports = [
 reactNativeBundle
];

与webpack一起使用时react-navigation未能捆绑
