如果你的ruby在非标准路径中,那么我个人喜欢在shell脚本中包装我的ruby调用,从而确保正确设置我的ruby程序所需的所有路径等,并在crontab中安排脚本。做点什么

2 * * * * /home/mark/project/ruby_wrapper_sh >> /home/mark/cronOutput.txt 2>&1

and your /home/mark/project/ruby_wrapper_sh should read something like

你的/ home / mark / project / ruby​​_wrapper_sh应该是这样的

and save, this simply working on my centos server. You can test the code first using this command before you edit your cronjob
