How is cron going to know which ruby to use? Cron uses a very minimalist
PATH. From crontab(5):
Several environment variables are set up automatically by the cron(8)
daemon. SHELL is set to /bin/sh, and LOGNAME and HOME are set from the
/etc/passwd line of the crontab's owner. PATH is set to
"/usr/bin:/bin". HOME, SHELL, and PATH may be overridden by settings
in the crontab; LOGNAME is the user that the job is running from, and
may not be changed.
Cron is going to look for /usr/bin/ruby or /bin/ruby and that's it,
unless there's more to this crontab that you haven't shown us.
If you need your crontab to use a specific version of ruby, on a system
with multiple versions installed, you need to use the full path to one
of them, or set the PATH variable.
