解决了，弄了好久，版本问题导致的，找到mardownx文件下的widgets.py文件下的render函数中，改两个地方

1,添加参数 renderer=None，

2.去掉c中的context

原因：Template.render()的参数必须是字典，弃用了Context

class MarkdownxWidget(forms.Textarea):

   def render(self, name, value, attrs=None, renderer=None):
       if 'class' in attrs.keys():
           attrs['class'] += ' markdownx-editor'
       else:
           attrs.update({'class':'markdownx-editor'})

       attrs['data-markdownx-editor-resizable'] = MARKDOWNX_EDITOR_RESIZABLE

       widget = super(MarkdownxWidget, self).render(name, value, attrs)

       t = get_template('markdownx/widget.html')
       c = ({
           'markdownx_editor': widget,
       })

       return t.render(c)

改了之后就能正常显示了
