django 中文语言和时区设置问题

我的django的版是3.0.2 

按照网上大牛的办法设置了还是不行，先记录在此

#开头定义
from django.utils.translation import gettext_lazy as _
#LANGUAGES_CODE前添加 
LANGUAGES = [
    ('zh-Hans', _('Chinese')),
]

LANGUAGE_CODE = 'zh-Hans'

仍然报错

?: (translation.E001) You have provided an invalid value for the LANGUAGE_CODE setting: 'zh_Hans'.
?: (translation.E004) You have provided a value for the LANGUAGE_CODE setting that is not in the LANGUAGES setting.

2020/3/8 找到另一篇文章，顺利解决这个问题

LANGUAGES = [
   ('zh-Hans', _('Chinese')),
]


LANGUAGE_CODE = 'zh-Hans'

TIME_ZONE = 'Asia/Shanghai'

USE_I18N = True

USE_L10N = True

USE_TZ = False

　　并在头部添加

from django.utils.translation import gettext_lazy as _

和以前的处理办法相比，其实是少了

use_TZ = False ,之前是true
