django 1.10.3 admin后台管理设置显示中文

在网上搜索的什么设置settings.py的LANGUAE_CODE，在1.10.3下完全不行，直接报错，后来使用了django.middleware.locale.LocaleMiddleware才可以

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.locale.LocaleMiddleware'
]

新增最后一行
