python小白，在看廖雪峰python subprocess教程的時(shí)候碰到下面一個(gè)執(zhí)行 nslookup 命令的報(bào)錯(cuò) 操作系統(tǒng)：win10 python版本：3.7 import subprocess print('$ nslookup') p = subprocess.Popen(['nslookup'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) output, err = p.communicate(b'set q=mx\npython.org\nexit\n') print(output.decode('utf-8')) print('Exit code:', p.returncode) 報(bào)錯(cuò)信息： $ nslookup Traceback (most recent call last): File "E:/py/learning-python/Process_Thread/multi_process/sub_process.py", line 14, in <module> print(output.decode('utf-8')) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc8 in position 2: invalid continuation byte Process finished with exit code 1 請(qǐng)問(wèn)造成這個(gè)錯(cuò)誤的原因是什么？如何解決謝謝。
