      If you're using bundler, please make sure you're on the latest bundler version:
          gem install bundler
          bundle update --bundler
      Then make sure your lock file includes this platform by running:
          bundle lock --add-platform #{platform}
          bundle install
      See `bundle lock --help` output for details.
      If you're still seeing this message after taking those steps, try running
      `bundle config` and ensure `force_ruby_platform` isn't set to `true`. See
      https://github.com/rails/tailwindcss-rails#check-bundle_force_ruby_platform
      for more details.
