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'

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:

Installing yarn using node package manager fixed the issue for me. Open command prompt and enter:
npm install -g yarn
