Clockwork / Clockworkd生成“rakefile.rb (查找: rakefile、Rakefile、rakefile.rb、Rakefile.rb)”

Question

我在后台用Clockworkd运行时钟。如果我只运行clockwork，它就会成功地执行rake命令。如果我通过clockworkd运行它，它会产生一个错误。我不知道为什么不管用。如有任何意见/建议，将不胜感激。

启动时钟

RAILS_ENV=production clockworkd -c lib/clock.rb start --log

错误

clock.rb

require 'clockwork'
require File.expand_path('../../config/boot', __FILE__)
require File.expand_path('../../config/environment', __FILE__)

include Clockwork

handler do |job|
  puts "Running #{job}"
end

every(1.hour, 'Get Updates') { `rake get_updates` }

Answer 1

运行rake get_updates任务的进程可能不在Rakefile所在的工作目录中。

您可以使用Dir.chdir '/dir/containing/Rakefile/'，或者使用-f选项显式地将路径传递给Rakefile：

every(1.hour, 'Get Updates') do
  Dir.chdir '/dir/containing/Rakefile/'
  `rake get_updates`
end
