進口問題

Question

我的virtualenv中我有很多使用圖書館的的依賴，但的paramiko和蟒蛇，keystoneclient提出這個導入錯誤：

我經歷了互聯網尋找解決這個問題的方法而不解決它。

我已經嘗試過這些步驟：

• 重新安裝任何圖書館參與
• 重新安裝的virtualenv
• 試圖用幾個舊的六個版本

這些的版本庫：

• 加密== 1.4
• keystoneauth1 == 2.8.0
• 的paramiko == 2.0.1
• 蟒-keystoneclient == 3.1.0
• 蟒-swiftclient == 3.0.0
• 6 = = 1.10.0
• urllib3 == 1.16

，我得到了這些Python版本相同的問題：

• Python的2.7.11+ - > Ubuntu的16.04
• Python的2.7.10 - > Ubuntu的15.10

如果我嘗試

from six.moves import urllib_parse 

Python的外殼內，它工作正常。

你有什麼想法嗎？提前致謝！

嘗試降級paramiko到1.16.0。對我來說這是一個解決方案。祝你好運！
