尝试在 Webpack 上将 mongoose 与 node-webkit 目标一起使用

Question

我使用 webpack 并将它的构建输出作为 node-webkit 的目标。我想要求我的项目中的 mongoose 模块连接到 mongodb，但是当我尝试打包项目时它总是提示一些错误：

似乎 webpack 无法加载 .node 文件，所以我安装了 node-loader 并添加到我的 webpack.config.js:

module.exports = {
    entry: './ui/index.jsx',
    target: 'node-webkit',
    output: {
        path: __dirname + '/build-ui',
        filename: 'app.js',
        publicPath: '/assets/'
    },
    module: {
        loaders: [
            {
                test: /\.jsx$/,
                loader: 'jsx-loader?insertPragma=React.DOM&harmony'
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader"
            },
            {
                test: /\.scss$/,
                loader: "style-loader!css-loader!sass-loader"
            },
            {
                test: /\.(png|jpg)$/,
                loader: 'url-loader?limit=8192'
            },
            {
                test: /\.json$/,
                loader: "json-loader"
            },
            {
                test: /\.target.mk$/,
                loader: "raw-loader"
            },
            {
                test: /\.node$/,
                loader: "node-loader"
            }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    }
};

但它仍然会抛出错误和警告。我错过了什么吗？

显示错误详细信息后，错误就很清楚了。

所以我只是忘了将 .node 添加到 resolve.extensions 数组中。
