devstack ContextualVersionConflict

Question

我有以下錯誤，一旦我在過去的穩定版本推出stack.sh：

它今天開始出現故障，試圖重新安裝Python的，但不知道什麼確切的問題

Answer 1

通過上面的日誌閱讀，由於版本衝突，它似乎是一個錯誤。

看行：ContextualVersionConflict: (keystoneauth1 2.4.3 (/usr/local/lib/python2.7/dist-packages), Requirement.parse('keystoneauth1>=2.16.0'), set(['castellan']))

要求是keystoneauth1> = 2.16.0，但您的系統包含keystoneauth1 2.4.3。

您需要做的是將keystoneauth1軟件包升級到最新版本，或者您可以卸載導致問題的軟件包，並且當您再次運行./stack.sh腳本時，安裝程​​序將自動安裝所需的軟件包。

$ sudo -H pip uninstall keystoneauth1 

我希望這可以解決您的問題。
