node.js - Error installing reactjs: Error unexpected end of JSON input while parsing near

Question

I tried installing reactjs via node using two different commands in the terminal using 1) npx create-react-app my-app and 2) npx create-react-app app

But both yielded the same error shown below:

Installing packages. This might take a couple of minutes.

Installing react, react-dom, and react-scripts with cra-template...

npm ERR! Unexpected end of JSON input while parsing near '....1","object-hash":"^1'

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

npm ERR! C:UsersDavidAppDataRoaming pm-cache_logs2020-02-12T03_53_37_836Z-debug.log

Aborting installation.

npm install --save --save-exact --loglevel error react react-dom react-scripts cra-template has failed.

I tried uninstalling and reinstalling node and also trying to install different older versions of reactjs but still got the same error. Also, I have tried clearing the node cache and then verifying it again via npm cache clear --force and then npm cache verify but still have not had any luck. Any help will be greatly appreciated.

The more detailed log shows this at the bottom:

Try running this in your terminal:

npm cache clean --force

And redo the thing you are doing
