我在端口80上运行了Nginx + Passenger + Rails，这需要使用sudo启动nginx。现在，当我使用whenever时，它也以sudo身份运行。我该如何避免这种情况？
以下是log/cron/error.log的日志：

我尝试手动运行cron作业，每当生成：
/bin/bash -l -c 'cd /Users/Passa/Documents/project && script/rails runner -e development '\''Subscription.renew_user_bandwidth'\'' >> log/cron/cron.log 2>> log/cron/error.log'
但最终收到此错误：
