next.js - 无法在 Vercel 上使用 serverSideTranslations

Question

在我的索引页面中，我正在使用 serverSideTranslations 函数。获取有关查找翻译文件的错误。此错误仅发生在 serverSideTranslations 使用的页面上。

我部署到 Vercel 和 Netlify。在他们两个我都有同样的错误。

在 _app.js 中我正在使用 appWithTranslation。

    return prodConfig;

next-i18next.config.js

module.exports = {

  },

您应该修改项目中的 next-i18next.config.js 文件，并将 path.resolve 添加到语言环境路径。您可以在 this 中查看示例 repo 。确保您知道您的语言环境文件夹所在的位置，并编写正确的路径。这个问题的答案在 this 中找到。 github线程。
