尝试在使用Webpack作为模块Bundler的nodejs应用程序中使用mongoose

我正在尝试将mongoDB集成到我的nodejs-react应用程序中。 我使用mongoose作为orm。
它从以下错误开始

WARNING in ./~/mongoose/~/mongodb/~/mongodb-core/~/bson/~/bson-ext/ext/index.js Module not found: Error: Cannot resolve 'file' or 'directory' ./win32/x64/bson in /Users/Johannes/Documents/Development/holmes/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/node_modules/bson/node_modules/bson-ext/ext @ ./~/mongoose/~/mongodb/~/mongodb-core/~/bson/~/bson-ext/ext/index.js 6:10-37 

我遇到了类似的问题在stackoverflow，并在我的webpackconfiguration文件进行了必要的更改

• 添加了节点和json加载器。

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

  {test：/.node$/，loader：'node-loader'}

• 添加了parsing和节点对象。

  解决：{

  扩展名：[''，'.js'，'.json'，'.jsx'，'.es6'，'.babel'，'.node']，

  modulesDirectories：['node_modules'，'app']}，

  节点：{

  控制台：是的，

  fs：'空'，

  网：“空”，

  tls：'空'}，

npm安装json-loader npm安装node-loader

以下是我的webpackconfiguration文件现在的样子。

 var path = require('path') var webpack = require('webpack') var autoprefixer = require('autoprefixer') var ExtractTextPlugin = require('extract-text-webpack-plugin') var assetPath = '/assets/' var absolutePath = path.join(__dirname, 'build', assetPath) module.exports = { devtool: 'cheap-module-eval-source-map', entry: [ 'webpack-hot-middleware/client', './src/index' ], target: 'node-webkit', output: { path: absolutePath, filename: 'bundle.js', publicPath: assetPath }, plugins: [ new webpack.optimize.OccurenceOrderPlugin(), new webpack.HotModuleReplacementPlugin(), new webpack.NoErrorsPlugin(), new ExtractTextPlugin("bundle.css") ], module: { loaders: [ { test: /\.js$/, loaders: [ 'babel' ], exclude: /node_modules/, include: path.join(__dirname, 'src') }, // fonts and svg { test: /\.woff(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/font-woff" }, { test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/font-woff" }, { test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/octet-stream" }, { test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: "file" }, { test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=image/svg+xml" }, { // images test: /\.(ico|jpe?g|png|gif)$/, loader: "file" }, { // for some modules like foundation test: /\.scss$/, exclude: [/node_modules/], // sassLoader will include node_modules explicitly loader: ExtractTextPlugin.extract("style", "css!postcss!sass?outputStyle=expanded") }, { test: /\.css$/, loader: ExtractTextPlugin.extract("style", "css!postcss") }, { test: /\.json$/, loader: 'json-loader' }, { test: /\.node$/, loader: 'node-loader' } ] }, resolve: { extensions: [ '', '.js', '.json', '.jsx', '.es6', '.babel', '.node'], modulesDirectories: [ 'node_modules', 'app' ] }, node: { console: true, fs: 'empty', net: 'empty', tls: 'empty' }, postcss: function(webpack) { return [ autoprefixer({browsers: ['last 2 versions', 'ie >= 9', 'and_chr >= 2.3']}) ] }, sassLoader: { includePaths: [path.resolve(__dirname, "node_modules")] } } 

所有的错误都消失了，但我仍然收到以下警告和捆绑没有得到生成。
