python - django.core.exceptions.ImproperlyConfigured : Requested setting USE_I18N, 但未配置设置

Question

我想将 MySQL 数据库连接到我的 django 项目，但它抛出一个错误:

"django.core.exceptions.ImproperlyConfigured: Requested setting USE_I18N, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings."

跟踪:

设置.py。

  DATABASES = {
        'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'test',
        'USER': 'user',
        'PASSWORD': 'root',
        'HOST':'',
        'PORT': '',
        }
     }

您必须定义相关变量以显示您的 settings.py 在哪里文件生活:

export DJANGO_SETTINGS_MODULE=mysite.settings

这是相关的docs条目:

When you use Django, you have to tell it which settings you’re using.Do this by using an environment variable, DJANGO_SETTINGS_MODULE.

The value of DJANGO_SETTINGS_MODULE should be in Python path syntax,e.g. mysite.settings. Note that the settings module should be on thePython import search path.

如果您使用的是 virtualenv (这是最好的做法)，你可以粘贴相关的export文件中的命令 <path-to-virtualenv>/bin/activate
