npm ERR! Unexpected end of JSON input while parsing near

You are trying to create a new angular, react, vue app, and you end up with an error message saying:

npm ERR! Unexpected end of JSON input while parsing near

There's a high chance that your npm cache been damaged.

Try:

npm cache clean --force

If you are a windows user, try deleting all files in this folder:

C:\Users{{your-username}}\AppData\Roaming\npm-cache

Then...

npm cache verify

If that doesn't work, try updating to the lastest (understand the risks)

npm i npm@latest -g

I hope this helps!

But i get this error for every single installation,
I tried with --cache to temporarily set another cache directory but still,
It happens everytime with me

Normally,
npm cache clean --force
solves the problem for most people.

If you scenario permits, you can consider a full uninstall of npm + delete the C:\Users{{your-username}}\AppData\Roaming\npm-cache folder.

Then re-install npm.

Finally, if nothing works for you, give yarnpkg.com/ a try.
You'll find yarn faster than npm :-)

[Krypton | Madhusudan Babar]

Yeah,
I already switched to yarn
Thanks 😇

[Rishi]

I'm a windows user n got the above error while running create-react-app on my terminal.
After deleting everything in npm-cache, then ran npm cache verify, the create-react-app command installed...
Thanks!

I had the same problem but npm cache clean --force didn't work for me. What I did was CLEAN MY PC using my cleaner(CCleaner) and npm install work now. I did it because the problem appears after I uninstall my node.js because I want to install nvm-windows on my PC (docs.microsoft.com/en-us/windows/n...), but after I did it I think some files and folders was leave behind making a conflict after I install node using nvm thus npm install do not work. So I thought cleaning my pc would solve the problem and it did.
These are just my thoughts. Hope to help someone.
