设置路径每当cron的，因此它可以找到红宝石 [英] Setting path for whenever in cron so it can find ruby

问题描述

我的红宝石是在/ usr / local / bin目录。 每当无法找到它，并在我的cron文件的顶部设置PATH也不管用，我想因为每当运行该命令新的bash实例内。

My ruby is in /usr/local/bin. whenever can't find it, and setting PATH at the top of my cron file doesn't work either, I think because whenever is running the command inside of a new bash instance.

# this does not work
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin

# Begin Whenever generated tasks for: foo
0 * * * * /bin/bash -l -c 'cd /srv/foo/releases/20110429110637 && script/rails runner -e production '\''ActiveRecord::SessionStore::Session.destroy_recent(15)'\'''

# End Whenever generated tasks for: foo

我如何知道无论何时何地我的红宝石二进制是什么？从/ usr / bin中制作一个符号链接似乎凌乱的我，但我想这可能是唯一的选择。

How can I tell whenever where my ruby binary is? Making a symbolic link from /usr/bin seems messy to me, but I guess that might be the only option.

更新 在这个页面的底部，我会尝试吧。

This question offers env :PATH, "..." in schedule.rb as a solution, but (a) I can't find any documentation of that feature anywhere in the docs (b) it doesn't seem to have solved the asker's problem (unfortunately it takes non-trivial turnaround time for me to just try it). update actually it is in the bottom of this page, i'll try it now.

更多信息

1. 我不能，因为它是由每当
生成修改cron命令

2. 我核实，如果我与的bash -l <​​/ code>一个新的bash shell是/ usr / bin中/ env的发现红宝石就好了


3. 我只是想在cron中的确切的命令，开始/斌/ bash中，从用户的命令行，它的工作。

1. I can't modify the cron command because it's generated by whenever
2. i verified that if I make a new bash shell with bash -l, /usr/bin/env finds ruby just fine
3. I just tried the exact command in cron, starting with /bin/bash, from the command line of that user, and it worked.

所以，这是非常神秘的...

so, this is very mysterious...

推荐答案

解决方案是把这个 schedule.rb ：
