在Windows上的npm啓動錯誤

我想用我的reactJS applciation編譯webpack和npm的文件。當我運行時：在Windows上的npm啓動錯誤

npm install --save react-websocket

它的工作正常。接下來當我執行

npm start

得到以下錯誤：

> [email protected] start D:\ReactServer 
> webpack-dev-server --hot 

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

錯誤說'webpack-dev-server'有點不對。從[webpack開發工具]（https://webpack.github.io/docs/installation.html#dev-tools）文檔看起來您需要另外安裝它。你是否？ – makadev

我想你沒有在你的系統上安裝webpack-dev-server。

npm install -g webpack-dev-server

在cmd/terminal上運行上述命令。希望它能解決你的問題。
