Compiled successfully!

You can now view my-app in the browser.

http://x86_64-apple-darwin13.4.0:3000

Note that the development build is not optimized.
To create a production build, use npm run build.

Mac OS
node: v14.9.0
npm: 6.14.7

I have the same problem!
I have tried deleting node_modules and doing "npm install" --> didn't help.
I uninstalled the node and reinstalled it --> didn't help

Would appreciate suggestions.

Found the solution at https://medium.com/@choy/fixing-create-react-app-when-npm-fails-to-start-because-your-host-environment-variable-is-being-4c8a9fa0b461:

1. Add "export HOST=localhost" to ~/.bash_profile
2. source ~/.bash_profile

typing unset HOST in the cmd line worked for me!
