I am trying to compile files with webpack and npm for my reactJS applciation. When I am running: 

npm install --save react-websocket

Its working fine. Next when I am executing

npm start

getting the following error:

> 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.

npm ERR! Or if that isn't available, you can get their info via:

npm ERR!     npm owner ls reactapp
npm ERR! There is likely additional logging output above.

npm ERR! Please include the following file with any support request:

Can anybody help me with this?

  • The error says `webpack-dev-server` is kinda missing. From [webpack dev-tools](https://webpack.github.io/docs/installation.html#dev-tools) Documentation it looks like you need to install it additionally. Did you? – makadev Nov 07 '16 at 13:23

I think you do not have webpack-dev-server installed on your system.

npm install -g webpack-dev-server

run the above command on cmd/terminal. Hopefully it will resolve your issue.

  • did you ran this command with cmd running as Admin?. try running it in the directory of your project where your package.json resides. run the following command. npm install webpack-dev-server – Rohail Najam Nov 10 '16 at 06:16
