使用OmniMarkupPreviewer出现问题

使用中直接使用预览报错

    Error: 404 Not Found

    Sorry, the requested URL 'http://127.0.0.1:51004/view/31' caused an error:

    'buffer_id(31) 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.

解决方法：Sublime Text > Preferences > Package Settings > OmniMarkupPreviewer > Settings - User 贴入如下代码即可

{
    "renderer_options-MarkdownRenderer": {
        "extensions": ["tables", "fenced_code", "codehilite"]
    }
}
