jekyll-redirect-from 和 github-metadata gems 的组合抛出错误

Question

我正在开发一个 Jekyll 网站，该网站使用 jekyll-redirect-from 将旧页面 URL 重定向到新的对应页面。它正常构建良好，但是当我也将 GitHub-metadata gem 添加到我的 gem 文件并尝试构建我的站点时，我收到一条非常无用的消息：

重要的部分是 no implicit conversion of Jekyll::GitHubMetadata::Value into String (TypeError) 部分。元数据 gem 似乎在某个地方放置了一个自定义对象，重定向 gem 期望有一个字符串，结果它爆炸了。

如果我删除任何引用 site.github.* 的所有实例，错误仍然存在。但是，如果我删除所有 redirect_froms，错误就会消失并成功构建。我对 Ruby 或这些 gem 中的任何一个都不太了解，因此无法进行很多故障排除。看起来罪魁祸首是 Jekyll-redirect-from gem.

中 redirector.rb 的 this line

我在 WasabiFan/curly-parakeet 有一个重现站点（"site" 的定义非常松散）。它会在 Windows 和新的 Ubuntu VM 上抛出上述错误。

可能是什么问题？这些 gem 之一是否有必须修复的内容？

P.S。作为这个问题的结果，我发现了 GitHub 的建议回购名称的用途。谢谢。
