高速公路无法导入名称错误

我使用安装了twisted和Autobahn websocket

pip install twisted
pip install autobahn

但是当我从Autobahn导入任何工厂时,我得到了无法导入名称的错误.

    >>> from twisted.internet import reactor
    >>> from autobahn.websocket import WebSocketClientFactory
    Traceback (most recent call last):
      File "", line 1, in 
    ImportError: cannot import name WebSocketClientFactory

有什么我想念的吗？这是冻结点

Twisted==13.2.0
Twisted-Core==12.3.0
Twisted-Names==12.3.0
Twisted-Web==12.3.0
autobahn==0.7.4
websocket==0.2.1
websocket-client==0.13.0

这看起来thoough WebSocketClientFactory是扭曲的子模块:

from autobahn.twisted.websocket import WebSocketClientFactory
