Make sure you have the following in your docusaurus config:
i18n: {
defaultLocale: 'en',
locales: ['en', 'fr'],
},
If you not init basic i18n config in your docusaurus config, you can checkout this url: https://docusaurus.io/docs/i18n/introduction
BTW: If you dont know what code should locales fill, you can fill it by reference this url: https://github.com/facebook/docusaurus/tree/main/packages/docusaurus-theme-translations/locales
Then:
Run this command:
OPENAI_API_KEY=sk-xxxxxx npx docusaurus-i18n
npx docusaurus-i18n --help
