Popen: NameError: name 'PIPE' is not defined

[Mathieu Prevot]

Hi

I import subprocess and use Popen, but PIPE is not defined. I used
2.5.1, 2.5.2, Python 2.6a3+ (trunk:63576, May 24 2008, 12:13:40), it's
always the same. What am I missing ?

Thanks
Mathieu

Without showing code, it's hard to know. A guess is: if you use

import subprocess


then use


subprocess.PIPE

Or if using

from subprocess import Popen

make sure to do

from subprocess import Popen, PIPE

Try subprocess.PIPE.
