有人遇到过这个问题吗？我该如何解决？ 我在CentOS上遇到过这个，django是1.9，我用的是uwsgi python是3.6 有没有人遇到过这个问题？我该如何解决？ 我在CentOS上遇到过这个，django是1.9，我用的是uwsgi python是3.6 谢谢！

最新的django-pagination 1.0.7于2010-05-06发布。 （另外Django 1.9不再支持我建议你升级到更新的版本或使用LTS版本。）但Django 1.9有自己内置的分页https://docs.djangoproject.com/en/1.9/topics/pagination/和Django 1.8 LTS和Django 1.11。我建议你使用内置的django.core.paginator并停止使用2010版的django-pagination。

从pagination的已安装应用中删除settings.py：
INSTALLED_APPS = [
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'pagination', //remove this line
'phone_field',
]
