Django管理命令Cron on Dotcloud

Question

我正在尝试运行cron来运行自定义的Django管理命令。我在DotCloud上运行。

当cron运行时，我得到以下错误：

Traceback (most recent call last):
File "./manage.py", line 2, in <module>
from django.core.management import execute_manager
ImportError: No module named django.core.management

我认为这是因为cron是在一个空环境中运行的，所以我尝试在同一个cron中手动设置PYTHONPATH。以下是该命令...

PYTHONPATH=/home/dotcloud/env/lib/python2.6/site-packages/setuptools-0.6c11-    
py2.6.egg:/home/dotcloud/env/lib/python2.6/site-packages/pip-1.0.1-        

py2.6.egg:/home/dotcloud/current:/home/dotcloud/env/lib/python2.6:/home/dotcloud/env/lib/python2.6/plat-linux2:/home/dotcloud/env/lib/python2.6/lib-tk:/home/dotcloud/env/lib/python2.6/lib-old:/home/dotcloud/env/lib/python2.6/lib-dynload:/usr/lib/python2.6:/usr/lib64/python2.6:/usr/lib/python2.6/plat-linux2:/usr/lib/python2.6/lib-tk:/usr/lib64/python2.6/lib-tk:/home/dotcloud/env/lib/python2.6/site-packages:/usr/local/lib/python2.6/dist-packages/virtualenv-1.6.1-py2.6.egg:/usr/local/lib/python2.6/site-packages:/usr/local/lib/python2.6/dist-packages:/usr/lib/python2.6/dist-packages:/usr/lib/pymodules/python2.6

错误仍在发生，我不确定发生了什么。任何建议都是非常感谢的。

谢谢。

您是对的: cron作业在“空”环境中运行。

而不是这样做：

* * * * * /home/dotcloud/current/myapp/manage.py args...

您应该这样做：

* * * * * /home/dotcloud/env/bin/python /home/dotcloud/current/myapp/manage.py args...

运行~/env/bin中包含的python解释器将自动设置正确的环境。
