here is the img description of the error
first it creates the folder (my-app), but after a few seconds it will be removed automatically. Either I installed the latest version of node.js.
$ npx create-react-app my-app

Could you try this,
Clear cache: npm cache clean --force
Install create-react-app globally: npm i create-react-app -g
Create your React project: create-react-app my-app
The problem should mostly be resolved with Step 1.

i updated my node thinking that may be the problem but still no change HELP!!
so i found the source to my problem. first i runed npm -g list and it only had npm no create-react-app so you need to install it using npm install -g create-react-app. check it by running npm -g list if successfully installed create-react-app will be their. now you can run npx create-react-app projctname with out a problem.

Ok it got fixed I had to uninstall node.js, delete all folders and re-install node.js and it worked!
npm version = 6.14.4
node version = v12.16.2

So, apparently the issue is from npm and non of us has done anything wrong.
try this : npm install -g --force create-react-app
if did not work,still we can use Yarn to start a new react project while they solve it, follow the steps:
step 1: yarn init -y
step 2: Insert this to package.json
"resolutions": {
"is-promise": "2.1.0",
"run-async/is-promise": "2.1.0"
}
step 3: yarn add --dev create-react-app
step 4: yarn create-react-app ../my-app
I was also facing almost same type of problem. But then tried
yarn create react-app my-app
in power shell with admin privilege which seemed to do the trick.
Also you’ll need to have Node >= 8.10, yarn >= 0.25+ on your machine as the official doc suggests. Hope this helps.
This is my first time trying out React and it's very demoralising to keep seeing the same error over and over again. I tried all three of these codes seperately
npx create-react-app myapp
npm init react-app myapp
npm install -g create-react-app then create-react-app myapp
All which gave me:
npm ERR! Unexpected end of JSON input while parsing near '...:"^5.0.0 || ^6.0.0"},'

Help!!!
You don't need react-app and other scripts
Simply:
npx create-react-app my-app
cd my-app
npm start
Refer: document of create-react-app

Update npm on your machine (Prasool advice):
sudo npm i -g npm
If it does not work as expected, please use
npm cache clean --force
as it seems to work for some around here and GitHub. :)
Have a happy coding time!
Can you retry after updating npm?
npm install -g npm
Please note that this command will remove your current version of npm. Make sure to use
sudo npm install -g npm if on a Mac.
