环境：python2.7

百度下，只有几个例子，有个说是某个函数被重新定义了，导致出问题。
我仔细看了下我的错误：
Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/eventlet-0.14.0-py2.7.egg/eventlet/hubs/hub.py", line 346, in fire_timers
timer()
File "/usr/local/lib/python2.7/dist-packages/eventlet-0.14.0-py2.7.egg/eventlet/hubs/timer.py", line 56, in __call__
cb(*args, **kw)
File "/usr/local/lib/python2.7/dist-packages/eventlet-0.14.0-py2.7.egg/eventlet/greenthread.py", line 194, in main
result = function(*args, **kwargs)
TypeError: 'tuple' object is not callable

然后通过一步步查询找到出错语句：
eventlet.spawn(utils.command(cmd))

在自定义的utils.command中，有调用subprocess.Popen和eventlet.sleep，可能是其中哪个出问题了
我因为对结果要求不高，直接将代码改为：
utils.command(cmd)

然后不再出错。
没有进一步查看原先的错处，个人考虑是某个函数重定义导致错误，不过网上也有代码不规范出错的
