[英]using python 2.7 to query sqlite3 database and getting “sqlite3 operational error no such table”
[英]Adding a database to the Django Project using Sqlite3 with Python 2.7
我正在嘗試使用Sqlite3和Python 2.7向Django項目添加數據庫。
這就是我的setting.py的樣子:
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.
}
}
它允許我創建數據庫,它要求我創建超級用戶:
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時,它會給我這個錯誤信息。
錯誤消息:

我如何解決上述錯誤? 為什么不允許我添加超級用戶? 我該怎么辦? 這可能是因為我在運行Python 2.7嗎?
在執行python manage.py syncdb之前鍵入this
export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
這將解決錯誤..順便說一句,我正在使用/ osr / bin / python中的mac os x python。
將其添加到./.bash_profile文件中,以便它自動調用它。
我最近在Windows上碰到了這個。 這是一個黑客,而不是修復或答案,但它可能會讓你解決你的問題:
將它放在manage.py腳本的頂部
import os
os.environ.setdefault('LANG','en_US')
