Issues with setting up react native cli project - ruby

Question

When I run npx react-native projectname, the project is only created partially.
Now when I run bundle install I get:
1. Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
2. An error occurred while installing ffi (1.15.5), and Bundler cannot continue. Make sure that "gem install ffi -v '1.15.5' --source 'https://rubygems.org/'" succeeds before bundling.

I am impressed how difficult it is to start a project. Someone please help

Answer 1

Try using expo. https://docs.expo.dev/get-started/create-a-new-app/
run npx create-expo-app my-app
this will create a new app called "my-app".
Or you could run npx create-expo-app --template to begin with a starter app. I like to use 'Navigation (TypeScript)'.
The expo link will explain how to set up your app and how to run your app in a simulator or with the expo go app on your phone. It's a great resource.
Hope that helped!
