Misaka Python:“super”对象没有“paragraph”属性

Question

我正在创建一个客户渲染器，以向Markdown添加警告标记。 我正在使用misaka。这是密码

import misaka as m
import re
import houdini as h


class CustomHTMLRenderer(m.HtmlRenderer):
    def paragraph(self, content):
        _prefix_re = re.compile(r'^\s*(!{1,4})\s+')

        CLASSES = {
            1: 'note',
            2: 'info',
            3: 'tip',
            4: 'warning',
        }

        match = _prefix_re.match(content)
        if match is None:
            return super(CustomHTMLRenderer, self).paragraph(content)  ## this call is the problem
        else:
            # do something
            pass

调用paragraph()方法时，我得到以下错误：

AttributeError: 'super' object has no attribute 'paragraph'
