    My advice is to try with with "rbenv". RVM can be quite troublesome sometimes.

    Installs with rbenv with brew:

    brew install rbenv ruby-build

    Configure your shell:

    # run this and follow the printed instructions:
rbenv init

    Install the Ruby version you want:

    rbenv install 2.7.4

    Set the Ruby version

    rbenv global 3.1.2   # set the default Ruby version for this machine
# or:
rbenv local 3.1.2    # set the Ruby version for this directory

    • The error message you provided suggests that there’s an issue with the installation of the ffi gem, which is required by Ruby.

    • First, make sure that you have the latest version of Xcode and the Command Line Tools installed. You can install them by running the following commands in your terminal:

      xcode-select --install
xcode-select -s /Applications/Xcode.app/Contents/Developer

    • Next,try installing the ffi gem manually by running the following command:

      sudo gem install ffi -v 1.13.1 -- --with-cflags="-Wno-error=implicit-function-declaration"
