无法在谷歌应用引擎上部署我的 reactjs webpack 应用程序

Question

我正在尝试部署我的反应应用程序，它是 100% 前端但在 webpack 服务器上运行。我需要将其作为灵活的环境部署到 Google 应用引擎，但在创建 gcloud app deploy 后出现此错误

我已关注this tutorial 并且所有依赖项都已安装。 不幸的是，我无法让它工作。

这是我目前的情况

server.js

 var webpack = require('webpack');
var WebpackDevServer = require('webpack-dev-server');
var config = require('./webpack.config');

new WebpackDevServer(webpack(config), {
  publicPath: config.output.publicPath,
  hot: true,
  historyApiFallback: true
}).listen(3000, 'localhost', function (err, result) {
  if (err) {
    return console.log(err);
  }

  console.log('Listening at http://localhost:3000/');
}); 

webpack.config.js

'use strict';

var path = require('path');
var webpack = require('webpack');
var env = process.env.NODE_ENV

module.exports = {
  devtool: 'eval',
  entry: [
    'whatwg-fetch',
    'webpack-dev-server/client?http://localhost:3000',
    'webpack/hot/dev-server',
    'babel-polyfill',
    './app/index'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    library: 'Redux',
    libraryTarget: 'umd',
    publicPath: '/static/'
  },
  plugins: [
   new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin()

  ],
  module: {
    loaders: [
      {  test: /\.js$/,
        loaders: ['babel-loader'], exclude: /node_modules/,
        include: path.join(__dirname, 'app')
      },

      {
            test: /\.json$/,
            loader: 'json'
        },

    {test: /\.scss$/, loader: "style-loader!raw-loader!sass-loader?includePaths[]=" + path.resolve(__dirname, "./node_modules/compass-mixins/lib") + "&includePaths[]=" + path.resolve(__dirname, "./mixins/app_mixins")},
  /*  { test: /\.scss$/, loaders: ['style', 'css', 'sass?includePaths[]=' + path.resolve(__dirname, './node_modules/compass-mixins/lib','raw']}, */
     { test: /\.css$/, loader: "style-loader!css-loader" },
     //{ test: /\.json$/, loader: 'json-loader' },
     { test: /\.(jpe?g|png|gif|svg)$/i,loader:'file'},
     {test: /\.(woff|woff2|ttf|eot)$/, loader: 'file'},
     { test: /\.(png|woff|woff2|eot|ttf|svg)(\?v=[0-9]\.[0-9]\.[0-9])?$/,loader: 'url' }



  ]
  },
  node: {
    fs: 'empty',
    net: 'empty',
    tls: 'empty'
  },

devtool: 'source-map'
};

package.json

"scripts": {
    "start": "node server.js",
    "bundle": "webpack --config webpack.config.js",
    "prestart": "npm run bundle",
    "lint": "eslint src"
  },

我做错了什么。

感谢您的帮助

Answer 1

您需要更改脚本。在 App Engine 中全局安装 Webpack 不是最好的方法，直接从 node_modules 使用。

首先，确保 webpack 在你的生产依赖中：

npm install --save webpack

编辑您的package.json 脚本：

"scripts": {
    "start": "node server.js",
    "bundle": "./node_modules/.bin/webpack --config webpack.config.js",
    "prestart": "npm run bundle"
},

现在一个简单的npm install 在干净的安装中就足以捆绑你的应用程序了。

Answer 2

您能否在package.json 文件中显示您的依赖关系？

我在运行 gcloud app deploy 时遇到了类似的问题

Error: Cannot find module 'webpack-dev-server'
at Function.Module._resolveFilename (module.js:469:15)

我解决了将 package.json 中的给定依赖项（wepack-dev-server）从 devDependencies 移动到 dependencies 的问题。

如果其他人有同样的问题，我建议查看 package.json 中的 dependencies。 dependencies 需要运行，devDependencies 仅用于开发，例如：单元测试、Coffeescript 到 Javascript 的转译、缩小，
