Windows上的npm启动错误

Question

我正在尝试使用webpack和npm为我的reactJS applciation编译文件。 当我跑步时：

npm install --save react-websocket

工作正常。 接下来我正在执行

npm start

收到以下错误：

> reactapp@1.0.0 start D:\ReactServer
> webpack-dev-server --hot

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

有人可以帮我吗？

Answer 1

我认为您的系统上没有安装webpack-dev-server。

npm install -g webpack-dev-server 

在cmd / terminal上运行上面的命令。希望它能解决您的问题。
