在Mac OS上嘗試通過crontab運行我的程序時遇到問題。我的程序獨立運行時工作正常。通常，我從不爲遠程系統密碼設置env.password。相反，我設置了env.key_filename。它工作正常，如果我不必運行sudo命令。所以理想情況下，它不應該提示任何密碼輸入。在crontab中運行Python Fabric命令時可能會回顯密碼輸入

通過參考https://github.com/fabric/fabric/issues/1230，我也嘗試設置環境變量來傳遞密碼。然而，我仍然得到同樣的錯誤。我錯過了什麼？任何人都可以幫忙嗎？

通過使用LaunchControl工具切換到launchd來關閉問題。這不是Fabric問題。 – Thomas

你可以發佈你的解決方案作爲答案，並自己接受 –

問題通過開關與LaunchControl工具封閉的launchd。這不是Fabric問題。

在crontab中運行Python Fabric命令時可能會回顯密碼輸入
