解决办法：

npm install webpack --save-dev

再次报错：

$ npm install webpack
npm ERR! code ENOSELF
npm ERR! Refusing to install package with name "webpack" under a package
npm ERR! also called "webpack". Did you name your project the same
npm ERR! as the dependency you're installing?
npm ERR!
npm ERR! For more information, see:
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
