In my own case since the project folder is created, i went to the ios folder

cd ios

and i open gem file and added this:

gem 'activesupport', '~> 6.1.5'

and then bundle install and it worked

You need to install the correct Ruby version. And it would be best if you use some ruby version manager for that. For example rbenv.

You can try these commands to install and change global Ruby version to 2.7.5

$ brew update
$ brew install ruby-build
$ brew install rbenv

$ rbenv install 2.7.5
$ rbenv global 2.7.5

After that, you need to export some configurations to define rbenv as default global ruby. For zsh users:

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(rbenv init -)"' >> ~/.zshrc

And restart the terminal or run source ~/.zshrc.

For bash users just replace zshrc with bashrc in the above.

If you are not able to find a fix to update the ruby version for a local project after going through the above solutions, I found one on ruby documentions. The rbenv documentation was also helpful to understand the issue.

RubyGems’ default local repository can be overridden with the GEM_PATH and GEM_HOME environment variables. GEM_HOME sets the default repository to install into. GEM_PATH allows multiple local repositories to be searched for gems.

Update the latest installed ruby version as default by copying the rbenv installed directory location found using gem env home and then past it in the ~/.zshrc file under export GEM_HOME=<directory-path>.

After this, if you check the ruby version inside your project you will get the latest global version set by you from rbenv, eg:- rbenv global 3.2.2.

Once the version is set in your local project you can install the bundler and update the cocoapods.

Just edit the Gemfile type nano Gemfile on terminal window to open Gemfile it should look like this

enter image description here

and just change ruby'2.7.5' version to which ruby version you want to specify your gemfile and control+X to save it you can specify your gemfile with any ruby version you need for the react native project 2.7.6 version is required for now

Welp, actually no answer solved my issue.
This happens even if your ruby version is correct when you run "npx react-native@latest init AwesomeProject". But I found the solution.
When you see this error, you will still see the project folder created. Go to the ios folder and run

bundle install && bundle exec pod install

problem solved.

Run this command inside the directory where you want to create the new app, to check the list of available ruby versions:

$ rvm list

if you get this message: # No rvm rubies installed yet. Try 'rvm help install'.

Then run:

$ rvm install 2.7.5 to install this specific version of ruby.

After installation is successful, run this command to make it default: $ rvm use ruby-2.7.5 --default

run again: $ rvm list to make sure that ruby-2.7.5 is selected as default

if you see something like this:

 =*ruby-2.7.5 [ x86_64 ]
   ruby-2.7.6 [ x86_64 ](other available version)
   ruby-3.0.0 [ x86_64 ](other available version)

# => - current
# =* - current && default
#  * - default

then you are good to go, you can safely run your command:

npx react-native init AwesomeProject

and everything should work as expected.

Can also use asdf to install it with asdf install ruby 2.7.5 (or whatever version is needed)

Then switch using asdf global ruby 2.7.5 and re-run your command.

See https://asdf-vm.com/guide/getting-started.html to get started with asdf

Found solution for me:

  1. Clear ~/Library/Caches folder
  2. Make sure you are using the latest required by react-native ruby version
ruby -v
  1. Reboot terminal and try again

check version of your ruby first

ruby -v

if isn't 2.7.5 you must roll your version to 2.7.5

rvm install "ruby-2.7.5"
rvm use ruby-2.7.5 --default

Below are the instructions which I have followed to solve this issue:

  1. Homebrew install: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  2. watchman install: brew install watchman
  3. Install Ruby: followed rbenv Official Github Repo link to install the required version of ruby
  4. Install CocoaPods: sudo gem install cocoapods
  5. CocoaPods in fixed location: sudo gem install -n /usr/local/bin ffi cocoapods

After the environment setup, it works perfectly.

As Alexander says use rbenv or rvm to manage your ruby version. MacOS automatically brings a native version of ruby. You should avoid to update or change your native (MacOS) ruby version.
