我需要
atexit.register一个函数来终止该过程：
import atexitprocess = subprocess.Popen(args.server_file_path)atexit.register(process.terminate)pid = process.pid
或许：
import atexitprocess = subprocess.Popen(args.server_file_path)@atexit.registerdef kill_process(): try: process.terminate() except OSError: pass #ignore the error. The OSError doesn't seem to be documented(?) #as such, it *might* be better to process.poll() and check for #`None` (meaning the process is still running), but that #introduces a race condition. I'm not sure which is better, #hopefully someone that knows more about this than I do can #comment.pid = process.pid
请注意，如果您进行了一些令人讨厌的操作，导致python以非优雅的方式死亡（例如，通过
os._exit或如果导致
SegmentationFault或
BusError），则这对您没有帮助
