使用Python 2.7使用Sqlite3向Django项目添加数据库

I am trying to add a database to the Django Project using Sqlite3 and Python 2.7.

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

This is how my setting.py looks like:

这就是我的设置。py看起来像:

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.
    }
}

It allows me to create the database and it asks me to create the superuser:

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):

When i type yes, it gives me this error msg.

当我输入yes时，它会给我这个错误msg。

Error msg:

How do i solve the error above? Why doesn't it allow me to add a superuser? what should i do? Could this problem because I am running Python 2.7?

如何解决上面的错误?为什么不允许我添加一个超级用户呢?我应该做什么?这个问题会不会因为我运行的是Python 2。7?

Type this before you execute the python manage.py syncdb

在执行python管理之前，请先输入这个。py syncdb

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

This will solve the error.. Btw i was using mac os x python which was in /usr/bin/python.

这将解决这个错误。顺便说一句，我用的是mac os x python，是/usr/bin/python。

Add it to the ./.bash_profile file so that it calls it automatically..

把它加到。/。bash_profile文件，以便它自动调用它。

I actually ran into this on windows recently. This is a hack, not a fix or an answer, but it might get you through your problem:

我最近在windows上碰到过这个。这是一个技巧，不是一个修复或答案，但它可能会帮你解决你的问题:

Put this at the top of your manage.py script

把这个放在你管理的最上面。py脚本

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