I had already install npm before, but somehow I had to uninstall it for some reason. Now, i tried to install npm again to create react app with this command.

npx create-react-app ip_tracker

On a halfway installation I found this error

npm ERR! code FETCH_ERROR npm ERR! errno FETCH_ERROR npm ERR! invalid json response body at https://registry.npmjs.org/@babel%2fpreset-react reason: Unexpected end of JSON input npm ERR! A complete log of this run can be found in: npm ERR! /home/ngebelcilik/.npm/_logs/2020-11-27T14_34_28_241Z-debug.log

Here's the logs

I already doing research on this error, it's similiar with this problem, but this problem happened everytime I install any npm packages (not just react).

    It might be a local caching issue. Can you please run npm cache clean --force and then try again? Commented Dec 1, 2020 at 4:25

Viral Patel comment solved it for me. Problem was solved by cleaning the local cache with.

npm cache clean --force

it didnt work for me
~ $ npm cache clean --force npm WARN using --force Recommended protections disabled.
This worked for me, but I had to do: sudo chown -R 501:20 'Users/[user_name]/.npm' first.

In my case I just ran the npm install again, it took a long time but it worked. It could have been a network issue.

npm ERR! invalid json response body at https://registry.npmjs.org/@babel%2fpreset-react reason: Unexpected end of JSON input

This means you are getting bad JSON in the response. There could be a number of reasons you get that error ranging from a network issue on your end to an issue with the npm servers. fwiw that resource does return valid json for me...

Try to curl the resource and see if the response is JSON:

curl https://registry.npmjs.org/@babel%2fpreset-react | python -m json.tool
