在我的 virtualenv 中，我有很多使用六个作为依赖项的库，但是paramiko和python-keystoneclient会引发此导入错误：

我通过互联网找到一种方法来解决这个问题而不解决它。
我已经尝试了这些步骤：
- 重新安装任何涉及的库
- 重新安装virtualenv
- 尝试了几个旧的六个版本
这些是库的版本：
- 密码学==1.4
- keystoneauth1==2.8.0
- 帕拉米科==2.0.1
- python-keystoneclient==3.1.0
- python-swiftclient==3.0.0
- 六==1.10.0
- urllib3==1.16
我对这些 Python 版本遇到了同样的问题：
- Python 2.7.11+ --> Ubuntu 16.04
- Python 2.7.10 --> Ubuntu 15.10
如果我尝试
from six.moves import urllib_parse
在 Python shell 中，它可以正常工作。
你有什么主意吗？提前致谢！
