#react #javascript #npm #git

Hello,

I have been trying to install React in my PC frfom past 24 hours and couldn't do it.
I followed the following procedure:

1) node.js in C drive
2) node version 12.16.1
3)npm version 6.14.2
4) Windows 10
5) then I followed: npx create-react-app my-app
6) cd my-app
7) npm start

But the following errors show up when I hit npm start

> my-app@0.1.0 start C:\Users\mohin\my-app
> react-scripts start

i ｢wds｣: Project is running at http://192.168.1.33/

I tried deleting node-modules and reinstalling and even cleared catche.
I tried every way I know but I couldn't find solution

I thought it was showing error for LIVE SERVER step so maybe I can still use it without live server but when i open index.html in public folder there is no output.

Please help me.

I really want to learn in this break quickly.

If your system is windows, set your environment variable, add %SystemRoot%\system32 to your PATH I met this error yesterday，hope it works to you. Don't forget reboot you PC

Hello,

I had to say thank you, I didn't find the solution, I tried all the method proposed in internet etc .. and now it work.
the question is :
before I add the environment variable, I work with angular I don't have the problem,
but when I switch to react native I get this problem why ?

and why we should add this %SystemRoot%\system32 to our PATH ?

Thank you
