python mongokit 连接() 断言错误

Question

我刚安装了mongokit，但不知道为什么会出现AssertionError这个错误。

这是在python控制台里的内容：

>>> from mongokit import Connection
>>> c = Connection()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.6/dist-packages/mongokit-0.5.3-py2.6.egg/mongokit/connection.py", line 35, in __init__
    super(Connection, self).__init__(*args, **kwargs)
  File "build/bdist.linux-i686/egg/pymongo/connection.py", line 169, in __init__

  File "build/bdist.linux-i686/egg/pymongo/helpers.py", line 98, in _unpack_response
AssertionError
>>> 

这是在mongodb控制台里的内容：

Wed Mar 31 10:27:34 connection accepted from 127.0.0.1:60480 #30
Wed Mar 31 10:27:34 end connection 127.0.0.1:60480

我使用的版本是：db 1.5，pymongo 1.5（我也测试过1.4），mongokit 0.5.3（还有0.5.2）。

Answer 1

这是一个在使用PyMongo连接MongoDB开发版本（大于1.4.0）时常见的问题。刚刚发布了PyMongo 1.5.2版本，里面修复了这个问题——你可以试着升级到这个版本。
