我正在编写一个使用 Open3 调用 perl 脚本的 Ruby on Rails 应用程序。但是，当调用 perl 脚本时，我的应用程序会比我想要的更快地引发 Timeout::Error。我调用脚本的代码如下所示：
Timeout::timeout(120){
@stdout, @stderr, @exit_code = Open3.capture3(@command)
[@exit_code.to_i, @stdout, @stderr]
}
我意识到调用一个潜在的“长时间”运行脚本（可能是 20-30 秒）对于 ruby on rails 应用程序来说并不理想，但我没有太多选择。
我正在使用独角兽来获得并发性，并且我将独角兽超时设置为 60 秒。尽管我的 unicorn 文件中有 60 秒超时，并且 Open3 调用周围有 120 秒超时，但我的请求仍然在 18 秒左右超时。我知道脚本已成功完成，因为我在另一边看到了结果，但我需要我的应用程序等待脚本返回。
有没有其他方法可以强制我的 Rails 应用程序等待而不是超时？
谢谢！
