      Cannot find the tailwindcss executable for #{platform} in #{exe_path}

      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-cjs#check-bundle_force_ruby_platform
      for more details.
