通过pdb调试djcelery的celeryd

有人尝试过使用 pdb 调试 celeryd 工作程序吗？每当遇到断点（通过 pdb 运行 celeryd，或者通过pdb.set_trace()），我遇到了以下错误：

Error while handling action event.
Traceback (most recent call last):
  File "/home/jeeyo/workspace3/uwcr/subscriptions/tasks.py", line 79, in process_action_event
    func(action_event)
  File "/home/jeeyo/workspace3/uwcr/subscriptions/tasks.py", line 36, in new_user_email
    send_registration_email(username, new_user.get_profile().plaintext_password)
  File "/home/jeeyo/workspace3/uwcr/looers/email.py", line 18, in send_registration_email
    'Your password from UWCoopRankings', user
  File "/home/jeeyo/workspace3/uwcr/looers/email.py", line 61, in send_email
    if isinstance(to, basestring):
  File "/home/jeeyo/workspace3/uwcr/looers/email.py", line 61, in send_email
    if isinstance(to, basestring):
  File "/usr/lib/python2.6/bdb.py", line 46, in trace_dispatch
    return self.dispatch_line(frame)
  File "/usr/lib/python2.6/bdb.py", line 65, in dispatch_line
    if self.quitting: raise BdbQuit
BdbQuit

有什么办法解决这个问题吗？

我有同样的问题。尝试使用 Celery 的远程调试器rdb反而：

from celery import task
from celery.contrib import rdb

@task()
def add(x, y):
    result = x + y
    rdb.set_trace()  # <- set break-point
    return result
