使用Sqlite3和Python 2.7將數據庫添加到Django項目中

Question

我試圖使用Sqlite3和Python 2.7將數據庫添加到Django項目中。

這是我setting.py看起來像：

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. 
    } 
} 

這使我可以創建數據庫，並要求我先打造超級用戶：

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): 

當我輸入yes，它給我這個錯誤消息。

錯誤消息：

我如何解決上述錯誤？爲什麼它不允許我添加超級用戶？我該怎麼辦？可以解決這個問題，因爲我正在運行Python 2.7？

Answer 1

本型的頂部將這個您執行的Python manage.py執行syncdb

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

之前，這將解決這個錯誤..順便說一句我使用這是在/ usr/bin中/ Python的Mac OS X的蟒蛇。

將它添加到./.bash_profile文件，以便它會自動調用它..

Answer 2

我最近在Windows上碰到過這個問題。這是一個黑客，而不是修復或答案，但它可能讓你通過你的問題：

在你的manage.py腳本

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