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
