我最近刚刚在我的jekyll网站上进行了一系列升级，以获得一个安装插件，现在当我开始构建时，我得到了这个：
`jekyll 3.4.3 | Error: undefined method `gsub' for 25:Integer`
完整堆栈是：

我不是最擅长这些东西，不知道这里发生了什么，或者如何解决它。 X-Code是最新的，我使用ruby包管理器让宝石一起工作，但仍然看到这个最终的错误。
有什么想法吗？谢谢！

安装后我遇到了同样的错误。去了jekyll-docs gem目录并运行...
jekyll serve
该命令退出...

因为已经在系统上安装了rouge。之后我跑了......
jekyll serve
瞧，瞧。它奏效了。结论：所需的依赖关系无法正确解析。

所以，另一个地方的朋友为我回答了这个问题！
我有一个帖子是下面的slu :: 25和Jekyll根本不喜欢这个，我把它改成了二十五个，这一切都很好！
希望这有助于其他人：）
