文件：

package.json

{
  "main": "./src/index.js",
  "scripts": {
    "start": "webpack --display-error-details --config ./webpack-config.js"
  },
  "devDependencies": {
    "webpack": "^3.0.0"
  },
  "dependencies": {
    "simple-oauth2": "^1.2.0"
  }
}

webpack-config.js

const path = require('path');

module.exports = {
  entry: path.resolve(__dirname, 'src/index.js'),
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  }
};

index.js

var simpleOauth2 = require('simple-oauth2');

当我运行npm start 时，我得到：

我已经阅读了有关在 webpack 中解析模块的内容，我已经尝试了几个 webpack 版本。如果不是加载simple-oauth2，而是加载lodash，它可以工作。 lodash 没有依赖关系，所以我最好的猜测是我当前的 webpack 配置无法处理 simple-oauth2 的依赖关系。

在理解从哪里开始解决这个问题时，我将不胜感激：)。

事实证明，我太天真了。这个simple-oauth2 库仅适用于 node.js，它不能像在浏览器中那样运行。

这就是http://browserify.org/ 的来源，例如：http://www.bradoncode.com/tutorials/browserify-tutorial-node-js/

一些 node.js 库的浏览器版本已经作为包提供，例如 request:
