New app "react-native start" return error without "sudo"

Description

Later I can’t init project without sudo until I saw this issue and run sudo chmod 777 /home/xxxxx/.babel.json, now I can init project without sudo (like react-native init AppName) but when I create a simple project (just a project init) and try running this by react-native start it’s return bellow message:

Loading dependency graph...(node:13642) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: EACCES: permission denied, open '/tmp/haste-map-react-native-packager-1-c06bcb90a866fe5fba0c98b29c4752c1'

When I use sudo react-native start it’s working well. Why it’s need sudo? How we can fix it?

Reproduction Steps

Create new project with:

react-native init TestApp

Change to this project directory:

cd TestApp

Try start app:

react-native start

Sample Code

Just simple hello world.

Solution

Run with sudo

I don’t understand so why it’s working well with sudo? 🤔

@hramos No because docs said that it’s optional.
