I downloaded my course react project, get into it, install dependencies and tried to run npm start. I got this nasty error:

PS C:\Users\Marcin & Joanna\Desktop\react-frontend-01-starting-setup> npm start

> frontend@0.1.0 start C:\Users\Marcin & Joanna\Desktop\react-frontend-01-starting-setup
> react-scripts start

operable program or batch file.

I tried with others project, same results. I tried to run npx-create-react-app my-app with no success, I got this error:

PS C:\Users\Marcin & Joanna\Desktop\mernStack> npx create-react-app frontend
Error: EPERM: operation not permitted, mkdir 'C:\Users\Marcin'
System nie może odnaleźć określonej ścieżki.
Instalacja [ 'create-react-app@latest' ] nie udała się, kod błędu: 1
PS C:\Users\Marcin & Joanna\Desktop\mernStack>

Those lines in Polish simply say:

System can not find specified path.

Installation [ 'create-react-app@latest' ]failed, error code 1.

I recently upgraded Node to version 14 and since then I got this issue. It doesn't matter which node version I install, I still got the same errors.

Remove & from the project path in: \ Marcin & Joanna

It is better to change the saved path of the project

did you try in the project directory:

npm install

or

npx autofix

or try to create your app in a different directory.
