    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:

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

    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.

    Further information why not to use system ruby and what are common issues: https://mac.install.guide/faq/do-not-use-mac-system-ruby/index.html

    I had the same problem with these exact versions. This was the solution for me: Fix Your Ruby version is 2.6.8, but your gemfile specified 2.5.5

    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

    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

    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

    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.

    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.
