__init_u2;（）接受1个位置参数，但在向标记添加Latex支持时，给出了2个位置参数

import markdown import cgi class MathJaxPattern(markdown.inlinepatterns.Pattern): def __init__(self, md): markdown.inlinepatterns.Pattern.__init__( self, r'(?<!\\)(\$\$?)(.+?)\2', md) def handleMatch(self, m): # Pass the math code through, unmodified except for basic entity # substitutions. # Stored in htmlStash so it doesn't get further processed by Markdown. text = cgi.escape(m.group(2) + m.group(3) + m.group(2)) return self.markdown.htmlStash.store(text) class MathJaxExtension(markdown.Extension): def extendMarkdown(self, md, md_globals): # Needs to come before escape matching because \ is pretty important # in LaTeX md.inlinePatterns.add('mathjax', MathJaxPattern(md), '<escape') def makeExtension(configs=[]): return MathJaxExtension(configs)

import markdown from django import template register = template.Library() @register.filter(name='markdown') def markdown_filter(value): return markdown.markdown( value, extensions=[ 'wagtailmd.mdx.mdx_mathjax', ], output_format='html5' )

{% extends 'base.html' %} {% load static %} {% load wagtailcore_tags wagtailimages_tags wagtailmd %} {% block content %}  <main> <div class="uk-container uk-container-small" style="margin: 0 auto;"> <article> <div class="math-editor"> {{ self.math_editor|markdown|safe }} </div> </article> </div> </main>  {% endblock content %} {% block extra_js %} <script type="text/x-mathjax-config"> MathJax.Hub.Config({ extensions: ["tex2jax.js"], jax: ["input/TeX", "output/HTML-CSS"], tex2jax: { inlineMath: [['$','$']], displayMath: [['$$','$$']] , processEscapes: true }, "HTML-CSS": { availableFonts: ["TeX"] } }); </script> <script type="text/javascript" src="//cdn.mathjax.org/mathjax/latest/MathJax.js"> </script> {% endblock %}

您的代码中有一个实现错误。根据markdown的documentation，应该定义要为自定义Extension提供的参数

如果您还没有任何配置，则应使用以下内容：

def makeExtension(configs={}):
    return MathJaxExtension(**configs)

完整的实现应该如下所示：

import markdown
import cgi

class MathJaxPattern(markdown.inlinepatterns.Pattern):
    def __init__(self, md):
        markdown.inlinepatterns.Pattern.__init__(
            self, r'(?<!\\)(\$\$?)(.+?)\2', md)

    def handleMatch(self, m):
        # Pass the math code through, unmodified except for basic entity 
        # substitutions. 
        # Stored in htmlStash so it doesn't get further processed by Markdown.
        text = cgi.escape(m.group(2) + m.group(3) + m.group(2))
        return self.markdown.htmlStash.store(text)

class MathJaxExtension(markdown.Extension):
    def __init__(self, **kwargs):
        self.config = {'option1' : ['value1', 'description1'],
                       'option2' : ['value2', 'description2'] }
        super(MathJaxExtension, self).__init__(**kwargs)

    def extendMarkdown(self, md, md_globals):
        # Needs to come before escape matching because \ is pretty important
        # in LaTeX
        md.inlinePatterns.add('mathjax', MathJaxPattern(md), '<escape')

def makeExtension(configs={}):
    return MathJaxExtension(**configs)
