Day07 jinja2模版文件TemplateSyntaxError: unexpected '}'

照着test.html敲进去或者直接copy test.html一直报jinja2.exceptions.TemplateSyntaxError: unexpected '}'

我的test.html如下，看着模版文件写的语法没问题呀
<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title>Test users - Awesome Python Webapp</title>
</head>
<body>
    <h1>All users</h1>
    {% for u in users %}
    <p>{{ u.name }} / {{ u.email }}</p>
    {% endfor %}
</body>
</html>
