Django-1.3 beta存在问题

Question

大家好!! 我非常热衷于学习Django并且学习了一些Django-1.2的内容，但是后来我安装了1.3版本，使用命令“python manage.py runserver”运行服务器时出现了一个巨大的错误，我无法解决这个问题。错误信息如下：

Traceback (most recent call last):    

  File "manage.py", line 11, in <module>    
    execute_manager(settings)    
  File "/usr/local/lib/python2.6/dist-packages/django/core/management/__init__.py", line 438, in execute_manager

你可能安装了两个版本的Django？ - programmersbook

你能在Python控制台中尝试一下这个代码（并报告结果）吗？import django django.VERSION - Tommaso Barbugli

耶！！我能够做到了，它显示为1.3版本... 我认为可能是django1.3-beta基于不兼容我的python 2.6的python3...但我不认为它是基于python-3.x。 - Mojo_Jojo

Answer 1

如果您安装了两个版本，则可能会发生这种情况。删除django (/usr/local/lib/python2.6/dist-packages/django)。只需删除整个文件夹。现在重新安装Django 1.3，它应该可以正常工作。

为了避免类似的问题，在以后的操作中使用 virtualenv。
