flask开中发遇到jinja2.exceptions.TemplateSyntaxError: unexpe

flask开中发遇到jinja2.exceptions.TemplateSyntaxError:

jinja2.exceptions.TemplateSyntaxError:?unexpected?'}',?expected?')'

提示告诉在jinjia模板中括号使用错误

代码:

{%?extends?"base.html"?%}
{%?import?"bootstrap/wtf.html"?as?wtf?%}
{%?import?'_marcos.html'?as?macros?%}
{%?block?title?%}Flasky{%?endblock?%}
{%?block?page_content?%}
<div?class="page-header">
????<h1>Hello,?{%?if?current_user.is_authenticated?%}{{?current_user.username?}}{%?else?%}Stranger{%?endif?%}!</h1>
</div>
<div>
????{%?if?current_user.can(Permission.WRITE_ARTICLES)?%}
????{{?wtf.quick_form(form)?}}
????{%?endif?%}
</div>
{%?include?'_posts.html'?%}
{%?if?pagination?%}
????<div?class="pagination">
????{{?macros.paginnation_widget(pagination,?".index"?}}
????</div>
{%?endblock?%}

经过检查发现原来是这句代码出错{{ macros.paginnation_widget(pagination,".index" }}中少了一个“)”

更正为:

{{?macros.paginnation_widget(pagination,?".index"?}}
