Gatsby sitemap.xml 和 RSS 提要使用错误的域名

Question

我将 Ghost 与 gatsby-starter-ghost 一起使用，并遇到了从 gatsby-plugin-advanced-sitemap 生成的 sitemap.xml 以及 RSS 提要 URL 的问题。
我的域名是https://www.officehomelife.com/并托管在 https://officehomelife.netlify.app/
问题是https://www.officehomelife.com/sitemap.xml正在根据 netlify 域名而不是我的域名生成 URL。它还使用 netlify 域名作为 RSS 提要 https://feedly.com/i/subscription/feed/https://officehomelife.netlify.app/rss/
我相信这个值应该来自 gatsby-starter-ghost\src\utils\siteConfig.js，我在那里定义了它:

    siteUrl: `https://www.officehomelife.com`, // Site domain. Do not include a trailing slash!

    postsPerPage: 12, // Number of posts shown on paginated pages (changes this requires sometimes to delete the cache)

    siteTitleMeta: `Office Home Life`, // This allows an alternative site title for meta data for pages.
    siteDescriptionMeta: `The essential guide to working from home`, // This allows an alternative site description for meta data for pages.

    shareImageWidth: 1000, // Change to the width of your default share image
    shareImageHeight: 523, // Change to the height of your default share image

    shortTitle: `Office`, // Used for App manifest e.g. Mobile Home Screen
    siteIcon: `favicon.png`, // Logo in /static dir used for SEO, RSS, and App manifest
    backgroundColor: `#e9e9e9`, // Used for Offline Manifest
    themeColor: `#15171A`, // Used for Offline Manifest
}

我尝试删除 .cache 文件夹，但这没有帮助，还有其他想法吗？
谢谢

Dealing with environment variables这有点棘手，你必须在变量前加上 GATSBY_使它们可用于浏览器端的服务器(Netlify):

In addition to these Project Environment Variables defined in .env.*files, you could also define OS Env Vars. OS Env Vars which areprefixed with GATSBY_ will become available in browser JavaScript.

那么，您的 process.env.SITEURL应该变成:

siteMetadata: { siteUrl: process.env.GATSBY_SITEURL || config.siteUrl, }

其余的环境变量依此类推。
