Webpack Express无法解析模块“ fs”，请求依赖关系为表达式

当我在项目中包含Express时，尝试使用webpack进行编译时总是会遇到这些错误。

webpack.config.dev.js

var path = require("path")

module.exports = {
  entry: {
    "server": "./server/server.ts"
  },
  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "bundle.js",
    publicPath: "/public/"
  },
  module: {
    loaders: [
      {
        test: /\.ts(x?)$/,
        exclude: /node_modules/,
        loader: "ts-loader"
      }, {
        test: /\.js(x?)$/,
        exclude: /node_modules/,
        loader: "babel-loader"
      }, {
        test: /\.json$/,
        loader: "json-loader"
      }, {
        test: /\.scss$/,
        exclude: /node_modules/,
        loaders: ["style-loader", "css-loader", "postcss-loader", "sass-loader"]
      }, {
        test: /\.css$/,
        loader: ["style-loader", "css-loader", "postcss-loader"]
      }, {
        test: /\.(jpe?g|gif|png|svg)$/i,
        loader: 'url-loader?limit=10000'
      }
    ]
  }
}

我试过了：

1. 安装“ fs”，但不起作用

2. 阅读某处以更改节点fs属性。它消除了错误警告，但我认为这不是一个很好的永久解决方案。

   module.exports = {
     node: {
       fs: "empty"
     }
   }
