我的 GitHub Pages 站点无法正确映射到我的自定义域，我该怎么办？

Question

我在我的 DNS 提供商中将

birdonelive.github.io

设置为 CNAME 记录，主机值为

www

并将

www.birdone.click

设置为 GitHub Pages 中的自定义域，这就是我得到的错误。

Both www.birdone.click and its alternate name are improperly configured
Your site's DNS settings are using a custom subdomain, www.birdone.click, that is set up as an A record. We recommend you change this to a CNAME record pointing to birdonelive.github.io. For more information, see documentation (InvalidARecordError).

我该怎么办？提前致谢。
