Duplicity Macos crontab（python 错误）

我在 macOS (crontab) 中运行 duplicity 时遇到错误

duplicity 命令如下（在命令行中有效）

/usr/local/bin/duplicity /Users/myname/go file:///Volumes/EVO840\ -\ IMPORTANT/DuplicityGo/ --exclude '**/bin/***' --exclude '**/pkg'

使用时crontab -e（带或不带 sudo），

* * * * * /Users/myname/bashscripts/duplicity.sh > /Users/myname/bashscripts/duplicity.log 2>&1

它返回以下错误

答案1

cron 通常没有或仅设置了有限的 PATH 环境变量。将其设置在 crontab 之上，设置为与在命令行中使用的相同值，错误可能会消失。

答案2

我发现问题出在我使用可移除卷作为欺骗的目的地。

为了使我的 bash 脚本正常工作（或者只是在 crontab 中运行 duplicity），我必须将 /bin/bash 添加到“完全磁盘访问”（不过，我觉得这不安全）
