Question

我正在跟随this Django教程，刚刚到达＆＃34;玩API＆＃34;需要通过自动设置环境变量的实用程序启动python交互式shell的部分。运行>>>python manage.py shell后，我得到：

C:\Users\datumZ\Anaconda\envs\myThai\lib\site-packages\django\db\backends\sqlite3\base.py:63: RuntimeWarning: SQLite received a naive datetime (2015-02-25 22:41:12.086961) while time zone support is active.

If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@scipy.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    c.Application.verbose_crash=True

我尝试通过直接设置DJANGO_SETTINGS_MODULE以及其他各种方法来绕过manage.py实用程序，但我更喜欢按照指示操作，因为我使用的是正确版本的python和Django。任何有关解决上面显示的界面错误的帮助都表示赞赏。

更新你的sqlite3库，你应该很好。看起来您的版本不支持转换日期时间对象。您可以通过在shell上执行以下操作来测试：

Python 2.7.5+ (default, Feb 27 2014, 19:37:08) 
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> import datetime
>>> db = sqlite3.connect('/tmp/sql.sqlite3')
>>> db.execute("""CREATE TABLE IF NOT EXISTS sessions (session integer
...                         primary key autoincrement, start timestamp,
...                         end timestamp, num_cmds integer, remark text)""")
>>> db.commit()
>>> cur = db.execute("""INSERT INTO sessions VALUES (NULL, ?, NULL,NULL, "") """, (datetime.datetime.now(),))
>>> cur.fetchall()
[]
>>> db.execute("""SELECT * FROM sessions""").fetchall()
[(1, u'2015-02-25 22:07:00.284058', None, None, u'')]

pip install -U sqlite3

这对我有用：

Python 2.7.5+ (default, Feb 27 2014, 19:37:08) 
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> sqlite3.sqlite_version
'3.7.17'
>>> sqlite3.version
'2.6.0'

无法使用Django的manage.py实用程序启动shell
