【问题描述】：

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

这就是我的 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):

当我输入是时，它给了我这个错误消息。

错误信息：

如何解决上述错误？为什么它不允许我添加超级用户？我该怎么办？这个问题可能是因为我运行的是 Python 2.7 吗？

【问题讨论】：

那么...您的问题是“如何在 OS X 上添加语言环境？”？
是因为我运行的是python 2.7吗？

标签： python database django python-2.7

【解决方案1】：

在执行 python manage.py syncdb 之前输入这个

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 文件中，以便它自动调用它..

【解决方案2】：

我最近实际上在 Windows 上遇到了这个问题。这是一个技巧，而不是修复或答案，但它可能会帮助您解决问题：

把它放在你的 manage.py 脚本的顶部

import os
os.environ.setdefault('LANG','en_US')
