如何通过 os.execl 重启scrapy spider

Question

Рlease 告诉我，如果出现错误，是否可以使用 os.execl() 重新启动蜘蛛？ 如果是这样，请举例说明如何执行此操作。 我的 go 代码的粗略示例

def parse(self, response):
    try
     ...
    except:
      os.execl("/usr/bin/scrapy", "crawl", "ruscale")
      os.kill(self.pid, signal.SIGKILL)

使用此代码我收到一个错误

    sys.exit(execute())
