我已按照https://github.com/thobbs/twissandra中的分步指南进行操作

我被困在python manage.py sync_cassandra收到消息的地方：

['/home/z/twissandra', '/home/z/twiss/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg', '/home/z/twiss/lib/python2.6/site-packages/pip-0.8.2-py2.6.egg', '/home/z/twiss/lib/python2.6', '/home/z/twiss/lib/python2.6/plat-linux2', '/home/z/twiss/lib/python2.6/lib-tk', '/home/z/twiss/lib/python2.6/lib-old', '/home/z/twiss/lib/python2.6/lib-dynload', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/home/z/twiss/lib/python2.6/site-packages', '/usr/local/lib/python2.6/dist-packages/pycassa-1.0.5-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/virtualenv-1.5.1-py2.6.egg', '/usr/local/lib/python2.6/site-packages', '/usr/local/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/python2.6/dist-packages/gst-0.10', '/usr/lib/pymodules/python2.6', '/usr/lib/python2.6/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.6/gtk-2.0']

    sys.describe_keyspace('Twissandra')
AttributeError: 'SystemManager' object has no attribute 'describe_keyspace'

我对此一无所知。该怎么办？

我只是注意到我从未将 sync_cassandra 分支（它解决了这个问题）合并到我的主分支中，因为我希望 ericflo 能够更快地接受拉取请求。

我刚刚合并了，所以拉主分支再试一次。顺便说一句，对于这个问题，github 可能比 SO 更合适。

小提示，如果您在 Python 中遇到此错误并且您不知道原因，请检查循环导入。这就是我的问题所在。

循环导入例如模块 A 导入模块 B 和模块 B 导入模块 A。在某些情况下这不起作用。
