How to generate mutilple languages pages when default language page files changed

[findlay-best-wishes]

I exec astro-generate when default language pages files changed, but astro-generate could emit the change of default languages pages files. such as:

// package.json
"scripts": {
    "dev": "astro dev",
    "start": "astro dev",
    "build": "astro build",
    "preview": "astro preview",
    "astro": "astro",
    "gen:i18n": "astro-i18next generate"
  },

// genI18n.js
chokidar
  .watch(['src/pages/**/*', '!src/pages/en/**/*'])
  .on('all', (event, path) => {
    console.log(event, path, 'timeout gen i18n pages');
    execSync('npm run gen:i18n')
    // generate('', 'zh', 'en')
  });
