Same problem here, however I'm using Mac!

What does your mix-manifest.json file look like?

[gerciljunio]

Sorry, I forgot to inform, here for me it was resolved by deleting the files:

public/mix-manifest.json
public/css/app.css
public/js/app.js

After removing, I deleted the folder node_modules, installed all the packages again with npm install and finished! Worked perfectly.

But anyway my mix-manifest.json file before solving the problem, was always empty.

[renjithspace]

Just delete
public/mix-manifest.json

and then run
npm run watch-poll or npm run dev

It will work fine!

I'm posting this here in case others have issues with this on Windows 10.
I kept receiving this error on a fresh install and tried all the various fixes. None of them worked. Until I noticed that 'npm run dev' was looking at a package.json file in my Windows user directory. It was empty and simply deleting it fixed my issues.

I ran this command and awesome, error has gone.
npm cache clean --force

while installing webpack using npm I am getting the following problem:

C:\Users\jhapi\Desktop\Reactjs>npm install --save-dev webpack
npm ERR! Unexpected end of JSON input while parsing near '...le-loader":"0.1.x","s'

npm ERR! A complete log of this run can be found in:
