使用jekyll与--watch标志导致构建错误

我在Windows 8上使用Jekyll来处理一个小项目.到目前为止,我喜欢Jekyll,但在尝试使用--watch标志服务我的网站时遇到了一个问题,这允许网站在对代码进行更改时更新.

当我运行我的杰奇的网站,我会打开我的cmd和cd正确的目录.根据Jekyll文档,我将chcp 65001在目录中执行以将编码更改为UTF-8.现在,当我运行jekyll serve -w或jekyll serve --watch收到包含以下内容的错误转储时:

值得注意的是,当我简单地运行网站时jekyll serve,没有--watch或-w标记,网站建立并为端口4000提供良好的服务.但是,这对于开发来说并不理想.
