![Python'subprocess'CalledProcessError：命令'[…]'返回非零退出状态1 [重复]](http://www.mshxw.com/aiimages/31/456039.png "Python'subprocess'CalledProcessError：命令'[…]'返回非零退出状态1 [重复]")
subprocess.check_output提出CalledProcessError上非零退出代码，
ping返回非零退出代码，如果事情是错误的（如未知的域名或网站关闭，或者网站有ICMP阻塞出于某种原因，或者您的Internet连接已断开）
。
如果要检查输出和退出代码，请使用subprocess.Popen：
import subprocessimport syssite = sys.argv[1]ping_count = 4process = subprocess.Popen(['ping', site, '-c', str(ping_count)], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)returnpre = process.wait()print('ping returned {0}'.format(returnpre))print(process.stdout.read())例子：
