Troubleshooting 'gem install jekyll ffi building native extensions' Issues on macOS

When attempting to install Jekyll using the command `gem install jekyll`, you may encounter errors related to building native extensions, specifically with FFI (Foreign Function Interface). This issue is particularly common on macOS, where Ruby is installed via Homebrew or another package manager.

To resolve this issue, you can try a few troubleshooting steps:

1. Update your PATH environment variable: If Ruby is not in your system's PATH, you'll need to update it manually. To do so, run the following command: `echo 'export PATH='/usr/local/opt/ruby/bin:$PATH'' > ~/.zshrc`. This will add Ruby to your PATH.

2. Set compiler flags for Ruby: You may need to set the LDFLAGS and CPPFLAGS environment variables to point to the correct locations of Ruby's include and lib directories. Run the following commands: `export LDFLAGS='-L/usr/local/opt/ruby/lib'` and `export CPPFLAGS='-I/usr/local/opt/ruby/include'`.

3. Reinstall Ruby: If you're using a package manager like Homebrew, you can try reinstalling Ruby by running `brew reinstall ruby`. This will remove the current version of Ruby and install a fresh one.

4. Update your gem sources: Run the command `gem sources -a` to add the default gem sources, then `gem sources -r` to remove any invalid sources. Finally, run `gem update --system` to update your Gemfile.

5. Run Jekyll installation again: After making these changes, try running the original command `gem install jekyll` again.

Additionally, ensure that you have Ruby version 2.4.0 or higher installed, as Jekyll-Sass-Converter requires it. You can check your Ruby version by running `ruby -v`.

Remember to be patient during the installation process, as building native extensions can take some time. If you encounter any further issues, feel free to consult the official Jekyll documentation or seek assistance from a Ruby expert.
