Use the command suggested in the error message: setup.py --help-commands You have to give setup.py a command argument; it cannot be run without any arguments. That command should give you a list and explanation from which you can figure out which command you want.

[Pythonmac-SIG] using the "PyUSB" module
I am a new MacPython (ver 2.6.1) user who has downloaded the "PyUSB" module, but am unclear about how to make it available for use in a program. Included among the downloaded files is 'setup.py' (and 'setup.pyc'). Running 'setup.py' via IDLE yields the following error msg: --- Traceback (most recent call last): File "/Applications/Python 2.6/pyusb-0.4.1/setup.py", line 62, in ext_modules = [usbmodule]) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/distutils/core.py", line 140, in setup raise SystemExit, gen_usage(dist.script_name) + "\nerror: %s" % msg SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: setup.py --help [cmd1 cmd2 ...] or: setup.py --help-commands or: setup.py cmd --help error: no commands supplied --- It seemed that 'setup.py' should be run in order to access functions in the PyUSB module, but perhaps I misunderstand the process. It would be appreciated if someone could suggest a related reference to read.

Everything is the same, except the wxPython version. Any ideas?
Paul
I recall getting an "Unknown load command" message from py2app after I
compiled the Reportlab extension *_renderPM.so* as a universal binary
under OS X 10.5 (Leopard) and tried to include it in the app. When I
compiled it again under 10.4 (Tiger), py2app (running under 10.5)
accepted it without any problem. I didn't (have time to) investigate any
further, only to note that the 10.5-built version was only 240 Kb
compared to 560Kb for the working, 10.4-built version.
Maybe there are extensions in wxPython 2.8.9.2 built using OS X 10.5
that were previously built using 10.4 and causing a similar problem?
Later
I have just rerun py2app with my original 10.5-built *_renderPM.so*
and -apart from me using a slightly earlier version of py2app than Paul
- it produces the self same error word for word (see attachments).
Could it be *_renderPM.so* itself that is causing your error Paul?

This is a hack - NSFileHandlingPanelCancelButton is 0, so trying to
match the tag like this will match all buttons with no tag assigned
(as is the default in Interface Builder). In addition, it assumes
that the button is a direct descendant of the window's content view -
since 2002 when the code above was written, it is no longer the case,
so that code is already broken on OS X 10.5.
That said, if you really must, a better way would be to check the
control's action rather than its tag, searching through the entire
hierarchy - something like this.
def buttons_with_action(view, action):
for subview in view.subviews():
if isinstance(subview, NSButton) and subview.action() == action:
yield subview
for i in buttons_with_action(subview, action):
yield i
cancelButtons = list(buttons_with_action(openPanel.contentView(), 'cancel:'))
if len(cancelButtons) != 1:
pass # handle error
cancelButtons[0].setTitle_('Go Away')
openPanel.runModalForTypes_(None)
and assuming you're going to be distributing your app, make sure you
handle the case when the button isn't there, or there are two of them,
or the button doesn't have a title, or something else weird happens in
a future OS version.

op.setPrompt_('foo') will change Open. Note that NSOpenPanel inherits
from NSSavePanel and a bunch of the API you might be looking for is in
NSSavePanel.
I don't believe it's possible to change 'Cancel' (beyond localizing
it).
Thanks Nicholas, it works for the "Open" button.
I found the following cocoa reference for the "Cancel" button :
