Python 6库的导入问题

Question

在我的虚拟环境中，我有很多库使用6作为依赖项，但是paramiko和python会引发这个导入错误：

ERROR:paramiko.transport:Unknown exception: cannot import name urllib_parse

我通过互联网想办法解决这个问题而不解决它。

我已经尝试过这些步骤：

• 重新安装任何涉及的库
• 重新安装虚拟主机
• 尝试了几个旧的六个版本

这些是库的版本：

• cryptography==1.4
• keystoneauth1==2.8.0
• paramiko==2.0.1
• python-keystoneclient==3.1.0
• ==3.0.0
• six==1.10.0
• urllib3==1.16

在这些Python版本中，我也遇到了同样的问题：

• Python 2.7.11+ ->Ubuntu16.04
• Python 2.7.10 -> Ubuntu 15.10

如果我试着

from six.moves import urllib_parse

在Python中，它正确工作。

你有什么想法吗？提前感谢！

试着把paramiko的评级降到1.16.0。对我来说这是个解决方案。祝好运!
