Django Tutorial - ImproperlyConfigured exception (pytz isn't installed)

问题

I'm currently working through the official Django tutorial using version 1.6.1 and version 2.7.5 of python on OSX. I'm working on part 2, which is the admin interface. When I attempt to go to /admin/polls/poll/, I get the following error report:

ImproperlyConfigured at /admin/polls/poll/
This query requires pytz, but it isn't installed.
Request Method: GET
Request URL:    http://127.0.0.1:8000/admin/polls/poll/
Django Version: 1.6.1
Exception Type: ImproperlyConfigured
Exception Value:    
This query requires pytz, but it isn't installed.
Exception Location: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py in datetime_trunc_sql, line 196
Python Executable:  /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python
Python Version: 2.7.5

I attempted to install pytz by installing pip (which required installing setuptools) but this made no difference. Also, I am going through this tutorial for a second time, and I know I didn't run into this problem a month ago. Could updating to Mavericks have caused some problem?

回答1:

I was also getting the same error. I installed pytz

$ pip install pytz

and then i restarted the server. The exception is no more now.

回答2:

After continuing to search for django and pytz, I found the 1.6 Django release notes, which mention that you must now install pytz to work with Sqlite3 if USE_TZ=True in your settings.py.

I don't know what effect USE_TZ has on your application, but setting that value to False allows me to proceed in the tutorial. I would hope that the Django tutorial is updated to reflect this change.

回答3:

The solution is very simple..

pip install pytz

and then stop and restart your server

回答4:

I had same error, then I installed pytz with pip install pytz and again had same error until I restarted WSGI instance. (eg. touching wsig.py (touch wsgi.py) or restarting apache (apache2ctl restart)
