sublime使用markdown预览显示404 not fou

当我在sublime 使用OmniMarkupPreviewer预览markdown文件时，报了下面的错误

Error: 404 Not Found

Sorry, the requested URL'http://127.0.0.1:51005/view/28'caused an error:

'buffer_id(28) is not valid (closed or unsupported file format)'

**NOTE:** If you run multiple instances of Sublime Text, you may want to adjust

the `server_port` option in order to get this plugin work again.

经过查找资料，找到了解决办法

Sublime Text > Preferences > Package Settings > OmniMarkupPreviewer > Settings - User

按上面那个顺序打开配置文件，把下面的代码粘贴进去

{

                 "renderer_options-MarkdownRenderer": {

                                 "extensions": ["tables", "fenced_code", "codehilite"]

                 }

}

重启sublime就好了
