使用带有Python 2.7的Sqlite3将数据库添加到Django项目

Question

我正在尝试使用Sqlite3和Python 2.7将数据库添加到Django项目中。

这是我的setting.py的样子：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'dev.db',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

它允许我创建数据库，并要求我创建超级用户：

You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no):

当我键入是时，它给了我这个错误消息。

错误消息：

我该如何解决以上错误？为什么不允许我添加超级用户？我该怎么办？因为我正在运行Python 2.7，所以可能出现此问题吗？

Answer 1

在执行python manage.py syncdb之前键入此

export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

这将解决错误。.顺便说一句，我使用的是/ usr / bin / python中的mac os x python。

将其添加到./.bash_profile文件，以便它自动调用它。
