导入错误

Question

我有运行我芹菜的任务，因为它无法找到我的模块中的一个问题：

(ff)bash-3.2$ flipfinder_app/manage.py celeryd 
[...]

ImportError: No module named adsense 

它确实存在：

(ff)bash-3.2$ pwd 
/Users/jasonlfunk/Workspace/Work/csm/ff-app/ff_app/apps/util 
(ff)bash-3.2$ ls | grep adsense 
adsense.py 

当我使用Django的壳，它进口罚款。

(ff)bash-3.2$ ff_app/manage.py shell

>>> from apps.util.adsense import has_adsense 
>>> has_adsense 
<function has_adsense at 0x10d3171b8> 

我已将此添加到任务文件：

import sys 
print sys.path 

，看到这个输出，当我尝试运行芹菜：

你可以看到，/Users/jasonlfunk/Workspace/Work/csm/ff-app/ff_app是路径，其是进口应该在哪里。

我ASLO已将此添加到任务文件：

import os 
os.chdir('/Users/jasonlfunk/Workspace/Work/csm/ff-app/ff_app') 

，一切工作正常。

发生了什么事？为什么cd到已经在我的路径中的目录解决了问题？有任何想法吗？

Answer 1

是from apps.util.adsense import has_adsense inside task def？
