This must mean that your package.json is broken.
I just had the same problem, and it fixed for me when I recreated/edited the package.json it is trying to access.
Type yarn init -y and read the package.json
Add the following lines:
"resolutions": {
"is-promse": "2.1.0",
"run-async/is-promise": "2.1.0"
}
Afterwards do yarn add --dev create-react-app and then try to compile your reactjs application using:
yarn create-react-app <PATH/APP-NAME>
I would also recommend trying to manually remove is-promise property. I think the command for that was called npm remove is-promise, but I am not sure.
But I am pretty sure that your package.json needs a fix :)
Reply if it didn't work, I'll try to find a different way-around then.
create-react-appis having a problem. Try uninstalling and reinstalling it.
