Answer 1

There are probably two things that can be at fault.

1. Poor internet connection.
2. outdated npm version.

update your npm and seek a strong internet connection.

Answer 2

If npx create-react-app my-app command not working and throws an error like: npm ERR! Unexpected end of JSON input while parsing near '...zAJNgZjZUkJ08ybAxwNnR', Just check your npm version:

npm --version 
npm -v

and if required update it:

npm install -g npm@latest

It will definitely work.

Answer 3

sudo npm i -g npx --force worked for me.

Answer 4

Its happened because of slow internet . So wait till ur internet connection is normal. Or install all dependencies one by one .

Answer 5

First check for npm version by running the following command npm --version. if you have an npm version then try instally npx globally with the help of npm i -g npx. if npm and ngx are installed properlly then this will work .
