Maybe you forgot to run npm iinstall ? Show your full package.json and webpack config file. — Karen Grigoryan
Hi Karen , I installed webpack globally as it was first installed locally and now its working fine — Webappsdeva

you need to install all dependencies from your package.json by running this command:

npm i

later you can run all of your scripts like this:

npm run start

I hope this would be helpful
