Ruby 升级后尝试生成Jekyll 3.4.3时出错

我最近在我的jekyll网站上进行了一系列升级，以安装一个插件，现在当我开始构建时，我得到了以下信息：

`jekyll 3.4.3 | Error:  undefined method `gsub' for 25:Integer`

完整堆栈是：

我对这些事情不是最熟练的，也不知道这里发生了什么，也不知道如何解决。X-Code是最新的，我正在使用ruby包管理器让gems一起工作，但仍然看到最后的错误

有什么想法吗？谢谢你

安装之后，我遇到了同样的错误。转到jekyll docs gem目录并运行

杰基尔发球

该命令以…退出
