代碼:的Python:subprocess.Popen - 沒有這樣的文件或目錄
#!/usr/bin/env python
import subprocess
cmd="ls -lrt"
process = subprocess.Popen(cmd, stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
(stdoutdata, stderrdata) = process.communicate()
print stdoutdata
錯誤:
Traceback (most recent call last):
File "test.py", line 5, in <module>
process = subprocess.Popen(cmd, stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
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
可有人請指教一下是與上面的代碼的問題?這是在process=subprocess.Popen
聲明失敗。
'Popen'預計列表'[ 「LS」, 「-lrt」]'(如果你不使用'殼= True') - 檢查文檔。 – furas
