python - 运行结构脚本抛出 ImportError : No module named celery

Question

我已经撕裂了很长一段时间了。

• 我在我的 virtualenv 中，我在那里安装了 celery==3.1.9。
• 我有一个默认的 celery/django 设置 ( http://celery.readthedocs.org/en/latest/django/first-steps-with-django.html )，它工作正常。

只要我运行任何结构脚本，它就会抛出 ImportError: No module named celery 源 self 的 proj/proj/celery.py 文件。这是怎么回事？

完整回溯:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/fabric/main.py", line 658, in main
    docstring, callables, default = load_fabfile(fabfile)
  File "/usr/local/lib/python2.7/dist-packages/fabric/main.py", line 165, in load_fabfile
    imported = importer(os.path.splitext(fabfile)[0])
  File "/home/username/Projects/proj/fabfile/__init__.py", line 2, in <module>
    from .staging import *
  File "/home/username/Projects/proj/fabfile/staging.py", line 3, in <module>
    from proj.settings.staging import DOMAIN, IP, USER, PASSWORD
  File "/home/username/Projects/proj/proj/__init__.py", line 5, in <module>
    from .celery import app as celery_app
  File "/home/username/Projects/proj/proj/celery.py", line 3, in <module>
    from celery import Celery
ImportError: No module named celery

编辑:我不认为我的结构脚本的内容与它有任何关系。为了举例我设置:

from fabric.api import local
def foo():
    local('echo bar')

调用 fab foo 引发 ImportError: No module named celery。实际上，如果我只调用 fab，结果是一样的。

我的proj/proj/__init__.py:

from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app

就像在 celery tutorial 中一样

编辑:

这个有效:

(venv)rg@dfi:~/Projects/proj$ python
Python 2.7.4 (default, Sep 26 2013, 03:20:26)

>>> from celery import Celery
>>>

解决方法是安装系统范围的 celery ，但这显然不是 fabric 所期望的行为。
