更新後在Ubuntu 14.04 LTS上的pip損壞

Question

更新後pip我現在看到以下錯誤日誌。我該如何解決它？我正在使用Python 2.7。

Traceback (most recent call last):

raise DistributionNotFound(req, requirers) 
pkg_resources.DistributionNotFound: The 'pip==7.1.0' distribution was not found and is required by the application 

Answer 1

我已通過以下過程解決它。

1： 下載pip 7.1.0 version並解壓到以下路徑

usr/local/lib/python2.7/dist-packages/pkg_resources 

第二： 使用以下命令

sudo chmod -R 777 python2.7/ 

那麼如果我用給可執行權限蟒蛇2.7目錄pip -V命令來檢查點的版本，它顯示我的版本7.1.0沒有任何錯誤日誌。
