With the following postcss.config.js:

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
};

This gem fails with the following message:

error: Script failed: see failed command above

However this syntax works as expected:

module.exports = {
  plugins: [
    require('tailwindcss'),
    require('autoprefixer'),
  ],
};
