为什么如果我运行subprocess.check_output('ls')
一切正常但是当我向命令添加参数时:subprocess.check_output('ls -la')
我收到错误:
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python2.7/subprocess.py", line 537, in check_output
process = Popen(stdout=PIPE, *popenargs, **kwargs)
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
如何将命令参数传递给subprocess.check_output()
?
