巧克力python安裝上AppVeyor失敗，1603

Question

我有安裝Python從巧克力味一個PS構建腳本：

choco install python -y 

但是，即使它可以在本地機器上AppVeyor運行就會失敗一半默默地：

日誌不告訴我任何有用的東西。這是巧克力的錯誤嗎，這個軟件包有問題，或者希望VM環境有問題？

從Microsoft documentation：

你可以，如果滿足下列條件之一爲真收到此錯誤信息：

• Windows安裝程序正在試圖安裝一個已安裝的應用程序的PC。
• 您嘗試安裝Windows Installer軟件包的文件夾已加密。
• 包含您嘗試安裝Windows Installer程序包的文件夾的驅動器作爲替代驅動器進行訪問。
• SYSTEM帳戶對您嘗試安裝Windows Installer程序包的文件夾沒有完全控制權限。您會注意到錯誤消息，因爲Windows Installer服務使用SYSTEM帳戶來安裝軟件。

錯誤的最可能的原因是，安裝程序不是由具有權限的用戶運行。
