}在 index.js 中添加，注意引用 loader 时，现在不支持缩写可能回报的异常
ERROR in ./index.js
Module not found: Error: Can't resolve 'style' in '/home/grandkai/Workspace/hello'
BREAKING CHANGE: It's no longer allowed to omit the '-loader' suffix when using loaders.
You need to specify 'style-loader' instead of 'style',
see https://webpack.js.org/guides/migrating/#automatic-loader-module-name-extension-removed
@ ./index.js 2:0-39var hello = require("./hello");
require("style-loader!css-loader!./index.css");
console.log(hello);
document.body.appendChild(document.createElement("div"));执行打包
