subprocess.Popen - 没有这样的文件或目录 [英] subprocess.Popen - No such file or directory

问题描述

代码:

import subprocess

process = subprocess.Popen('echo 5')

错误:

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    process = subprocess.Popen('echo 5')
  File "/usr/lib64/python2.6/subprocess.py", line 642, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.6/subprocess.py", line 1238, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

有人可以告诉我上面的代码有什么问题吗?

Can someone please advise what is the issue with the above code?

推荐答案

将代码改写如下

import subprocess

process = subprocess.Popen(['echo', '5'])

命令应该是一个列表
