我正在尝试使用上帝监视推文流守护程序。我的上帝配置非常简单：

path = File.expand_path(File.dirname(__FILE__))

God.watch do |w|
  w.name = "tweet.rb"
  w.start = "bundle exec ruby #{path}/tweet.rb start"
  w.keepalive
end

虽然我的 tweetstream 守护进程也是它的标准实现。当我启动上帝进程时，它似乎会一遍又一遍地循环启动进程……我不确定它是否无法启动，或者它是否无法启动开始然后关闭..或者我想我不知道如何解释这个..任何帮助表示赞赏：一些示例输出：

如果我删除 bundle exec 并只使用：

w.start = "ruby #{path}/tweet.rb start"

错误日志更改为：
