备份 gem 未按预期从 crontab 运行

Question

我在 /Users/***/Backup/models 中有 production_backup.rb 文件。

当我从终端执行以下命令时，我的数据库备份成功了

  backup perform --trigger production_backup

现在我有一个 ruby 脚本，代码如下 /Users/***/Backup/my_backup.rb

  cmd = "backup perform --trigger production_backup"
  exec cmd

当我将上面的代码作为如下 ruby 脚本执行时，备份已成功创建

  ruby my_backup.rb

现在我遇到了问题，当我想从我的 crontab 执行相同的 ruby 文件时，它不起作用。我的 crontab 包含

 33 13 * * * /usr/bin/ruby /Users/***/Backup/my_backup.rb >> /Users/***/Backup/cronoutput.log 2>&1

此作业在指定时间执行，但我在日志文件中收到以下错误，即

/Users/***/Backup/my_backup.rb:4:in `exec': No such file or directory - backup (Errno::ENOENT)
from /Users/***/Backup/my_backup.rb:4:in `<main>'

根据@honey 的建议，我更新了 crontab 以直接执行命令，但现在在日志中我收到以下错误

可以直接从crontab执行命令

 33 13 * * * /bin/bash -l -c 'backup perform -t production_backup' >> /Users/***/Backup/cronoutput.log 2>&1

将以下代码放入您的 /Users/***/Backup/config.rb

Utilities.configure do
  tar       '/usr/bin/tar'
  # redis_cli '/opt/redis/redis-cli'
  tar_dist :gnu
  pg_dump '/opt/homebrew/bin/pg_dump'
end
