"npm start" command with errors

[mastodontusrexus]

Hi guys,

I am following this REACT tutorial. I came across a problem while trying to install webpack-dev-server. NPM returned info that webpack-dev-server is now replaced by webpack-dev (which has been installed).

Nevertheless when I'm trying to run "npm script" I am being asked to instal webpack CLI which I am trying to do but there is a bunch of errors at the end.
Could any of you look at them and point me in the right direction please?

PS C:\Users\Prosiaczek\Desktop\react_app\react-playlist> npm start

[email protected] start C:\Users\Prosiaczek\Desktop\react_app\react-playlist
npm run build

[email protected] build C:\Users\Prosiaczek\Desktop\react_app\react-playlist
webpack -d && webpack-dev-server --content-base src/ --inline --hot --port 1234

The CLI moved into a separate package: webpack-cli
Would you like to install webpack-cli? (That will run npm install -D webpack-cli) (yes/NO)y

I think it has something to do with webpack. config.js

[AKASHAGARWAL0403]

I also faced the same issue.... this is due to the fact that you are using webpack v2 in webpack v1...
try to install the webpack version1 and do it.

@AKASHAGARWAL0, how do you know which webpack you have installed? And how do you install a different version?
