得不到 Ruby 每当工作

Question

我在让 whenever 在我的本地开发环境中工作时遇到了一些问题。我正在使用 mac OS 10.12、ruby 2.4、rails 5.1 和 whenever 0.10.0。

我的 schedule.rb 文件设置为：

set :environment, "development"
set :job_template, "TZ=\"America/Los_Angeles\" bash -l -c ':job'"
set :output, Whenever.path + "/log/cron.log"

every 5.minutes do
  runner "Test.new.run"
  command "/bin/echo 'Is this working?'"
end

crontab -l 输出如下：

# Begin Whenever generated tasks for: /Users/me/apps/Test/config/schedule.rb at: 2018-05-25 12:59:14 -0700
0,5,10,15,20,25,30,35,40,45,50,55 * * * * TZ="America/Los_Angeles" bash -l -c 'cd /Users/me/apps/Test && bundle exec bin/rails runner -e development '\''Test.new.run'\'' >> /Users/me/apps/Test/log/cron.log 2>&1'

0,5,10,15,20,25,30,35,40,45,50,55 * * * * TZ="America/Los_Angeles" bash -l -c '/bin/echo '\''Is this working?'\'' >> /Users/me/apps/Test/log/cron.log 2>&1'


# End Whenever generated tasks for: /Users/me/apps/Test/config/schedule.rb at: 2018-05-25 12:59:14 -0700

并且当我在终端中运行 mail 命令时收到以下信息：

  Message 1:
From me@box.local  Fri May 25 13:00:01 2018
X-Original-To: me
Delivered-To: me@box.local

X-Cron-Env: <USER=me>

Date: Fri, 25 May 2018 13:00:00 -0700 (PDT)

但是，我没有看到 cron.log 的任何输出，数据库也没有反映来自 Test.new.run

的任何 activity

不太确定我做错了什么...

我认为问题可能与 rvm 和我设置的 .rvmrc 文件有关，当我 cd 进入时加载了正确的 rvm 设置目录。

为了确保命令正常运行，打开了一个新终端 window 和运行：bash -l -c 'cd /Users/me/apps/Test && bundle exec bin/rails runner -e development '\''Test.new.run'\'' >> /Users/me/apps/Test/log/cron.log 2>&1'

首先出现的是标准的 1 off rvm 消息：

You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers,
you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version'
or ignore this warning with 'rvm rvmrc warning ignore /Users/me/apps/Test/.rvmrc',
'.rvmrc' will continue to be the default project file in RVM 1 and RVM 2,
to ignore the warning for all files run 'rvm rvmrc warning ignore all.rvmrcs'.

在我输入 y 并按下回车键后，cron 作业现在可以正常执行了。

不幸的是，我的 cron.log 文件中仍然没有看到任何内容。
