解决办法：
npm install webpack --save-dev
再次报错：
1 $ npm install webpack 2 npm ERR! code ENOSELF 3 npm ERR! Refusing to install package with name "webpack" under a package 4 npm ERR! also called "webpack". Did you name your project the same 5 npm ERR! as the dependency you're installing? 6 npm ERR! 7 npm ERR! For more information, see: 8 npm ERR! <https://docs.npmjs.com/cli/install#limitations-of-npms-install-algorithm>
原因是 package.json 文件中的 name 为 webpack，所以避免项目名称与插件名称重复
