npm - 'webpack-dev-server' 未被识别为内部或外部命令，

Question

我按照关于 pluralsight 的教程使用 gitbash 通过 github 克隆了这个 Webpack Starter 包。我正在尝试通过 Visual Studio Code 的集成终端访问 webpack，但出现以下错误。我是新手，所以请帮助我。

我正在运行命令

 Raza Zaidi@RazaZaidi-PC MINGW64 ~/webpack-starter (master)
$ npm run dev

然后发生以下错误

> yet-another-webpack-es6-starterkit@1.0.0 dev C:\Users\Raza Zaidi\webpack-starter
> webpack-dev-server --open --config webpack/webpack.config.dev.js

'webpack-dev-server' is not recognized as an internal or external command,
operable program or batch file.

Webpack 命令应位于以下位置:node_modules\.bin\
在这种情况下，在 package.json 文件中，我们指的是 webpack-dev-server，但本地 webpack-dev-server 不存在。

首先运行以下命令进行全局安装:

npm install -g webpack-dev-server

第二次执行本地安装命令，会创建 node_modules\.bin\webpack-dev-server :

npm install webpack-dev-server --save-dev
