I'm using node.js and webpack to create a bundle. From what I've read, node.js should contain fs module for managing files. However when I call require("fs") I get an Cannot find module "fs" error. What should I do?

推荐答案

我自己在与 webpack 捆绑时遇到了这个问题，并在 这个话题.

I came across this problem myself when bundling with webpack and found the answer on this thread.

为我解决它的方法是使用以下配置:

The way to solve it for me was to use the following config:

module.exports = {
  entry: "./app",
  output: {
    path: __dirname,
    filename: "bundle.js"
  },
  module: {
      loaders: [
          {  
              test: /.js$/,
              exclude: 'node_modules',
              loader: 'babel',
              query: {presets: ['es2015']},
          }
      ]
  },
  target: 'node'
};

通过将目标设置为 node webpack 将进行必要的更改以捆绑您的 node 应用程序

By setting target to node webpack will make the necessary changes to bundle your node application

此答案针对现已被取代的 webpack 1.x.
