Like, having webpack installed globally, caused some issues in the past. The idea was to list globally installed packages and search for packages like webpack, babel stuff, etc, and warn the user that they might cause problems. Even better, implement this in a separate command as well, like rnv doctor where we can add more stuff related to environment
