Module not found: Can't resolve './components/AddNumber' in '/Users/user/Desktop/reactpracticeall/react-redux/src/components'

Module not found: You attempted to import ../components/AddNumberRoot which falls outside of the project src/ directory. Relative imports outside of src/ are not supported.
