Trying to create a new react native project

Question

I want to create a new react native project. At first, I faced a problem when I ran npm install -g expo-cli and I solved it by installing nvm, then installing node and npm by nvm. When I ran expo init NewProject , I got this error. Could you help me solving it, please?

  Uncaught Error [Error: EACCES: permission denied, open 
'/home/pgf/.expo/state.json.1309825572'] {
  errno: -13,
  code: 'EACCES',
  syscall: 'open',
  path: '/home/pgf/.expo/state.json.1309825572'
}

I tried sudo expo init ; I got this ✖ Something when wrong installing JavaScript dependencies. Check your npm logs. Continuing to initialize the app. ✖ Something when wrong installing JavaScript dependencies. Check your npm logs. Continuing to initialize the app. and it created a project. Bur when I ran the project with expo start I got this error

and this error when I ran it with sudo expo start

Cannot determine which native SDK version your project uses because the module `expo` is not installed. Please install it with `yarn add expo` and try again.

Could you help me solving this?

For me, there was no need to run it with sudo, since I ran into permissions errors. I had to reinstall expo-cli globally without using sudo. After that in your project directory:

sudo rm -rf ~/.expo
npm run start
