Hi Frank,
I am trying to use this to run an external process and print th estdout to
a nuke.display dialogue, but I keep getting:
CRITICAL: Logging Unhandled Exception: OSError
Traceback (most recent call last):
File "<string>", line 23, in <module>
File
"/software/nuke/6.3v5/linux.centos5.x86_64/lib/python2.6/subprocess.py",
line 633, in __init__
errread, errwrite)
File
"/software/nuke/6.3v5/linux.centos5.x86_64/lib/python2.6/subprocess.py",
line 1139, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
and I have no idea what file or directory it's looking for. Any clues?
Even just having it as you have it exactly gives me this, am I being a bit
literal about PIPE?
