【问题描述】：

有人试过用 pdb 调试 celeryd worker 吗？每当遇到断点时（通过 pdb 或 pdb.set_trace() 运行 celeryd），我都会遇到以下错误：

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

有什么解决办法吗？

【参考方案1】：

我遇到了同样的问题。尝试改用 Celery 的远程调试器rdb：

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
