if there are other antivirus on your computer, try deleting them all.

No I don't have any other antivirus and also I tried everything. Nothing seems to work. I have been banging my head on this error for more than 2 days.

[rizwanullah313]

first you need to run this script npm install -g create-react-app

after that run npx create-react-app my-app

I have the same problem when i tried to run create-react-app. I'm still trying to solve it, but i can't find a solution.

I have the same problem when i tried to run create-react-app. I'm still trying to solve it, but i can't find a solution.

Hi, so I solved it by deleting Node modules from my local disk C and also the user folder. Removed everything related to npm. After that I restarted my computer and installed everything from scratch. Surprisingly it worked for me. Let me know how it goes

Let me try it. I'm deleting my user folder. I'll back here in some minutes.

[AasifFiraz]

If this still does not work clone a copy of the boilerplate code which is after you use npx create-react-app. Before I solved this I did this and worked for me. I'll send a GitHub boiler plate code Download you can use. Clone it and make sure to run npm install after u get the file on your computer to install all the modules, then run npm start and you will be good to go :)
