Subject: [Pythonmac-SIG] Dependency between pyobjc and py2app?
Message-ID: <6764E25B-12B4-415B-865A-3DE1FAD1C3F5@darwin.in-berlin.de>

Hi,

after a longer break I've been looking into PyObjC again, installed 
a fresh framework-built Python followed by the pyobjc package as de-
scribed here:

  http://pythonhosted.org/pyobjc/install.html

Then, running a few samples from this page:

  http://pythonhosted.org/pyobjc/examples/index.html

revealed that py2app was missing which I had to install seperately as 
Ronald kindly pointed out. 

So ok, this could clearly be better indicated on the installation page 
above, but what I really wonder is if pyobjc and py2app can be useful 
as stand-alone packages or if they are not so much tied to each other 
that there should be a dependency in pyobjc on py2app, installing the
latter automatically with the former?

Regards,

Dinu

I've created an issue for this <https://bitbucket.org/ronaldoussoren/pyobjc/issue/59/add-py2app-to-dependency-list-of-pyobjc>.

At the very least the installation of py2app should be mentioned in the installation manual for PyObjC and I agree that it would be better to just add py2app to the list of install_requires of the PyPI package "pyobjc". 

There is a usecase for not using py2app with pyobjc, for example folks using Xcode to build application bundles. However, py2app and its dependencies are very small and "forcing" users of pyobjc to install py2app as well isn't really a problem. 

If I get bored I'll probably create some Xcode templates that use py2app to do the work, but before I do that I need to finish pyobjc 3.0 :-)

That is bizarre; Python should not be touching /bin/ls at all (if you're at
all familiar with POSIX, 'ls' is the "list contents of directory" command).
I'd be more inclined to suspect that your XCode has been corrupted somehow;
perhaps reinstalling that might help. I wouldn't expect LLDB to depend on
Python either, but who knows.

I don't think your installation of Python 3.3 is at fault here, since as
you noted the error is dealing with Python 2.7. I believe that's simply the
OS built-in Python. You might try opening up a commandline in Terminal and
running this:

/Library/Frameworks/Python.framework/Versions/2.7/bin/python

which ought to run the 2.7 Python REPL (read-eval-print loop, a simple
program that lets you test out Python code). If that fails, then your OS
built-in Python has probably been damaged.

Hope that helps.

Does "/System/Library/Frameworks/Python.framework/Versions/2.7/Python" still exist? The error message appears to indicate that this file no longer exists, which would be bad.

Ronald,

Did you mean this to go to the list? I've forwarded it on...

Anyway, thanks for the notes -- I'll keep all this in mind when I
build that app again.

Now that i think about it again, I think MPL makes some optional use
of PIL -- that's probably it.

this is nice -- thanks!

I'll give that a shot.

I did probably use the wrong reply button :-(

Working with the dependency graph is currently too hard for humans, amongst other because there is too much detail. A number of people have started to use modulegraph outside of py2app and based on interactions on modulegraph's issue tracker I have some ideas to improve the situation.

In the long run there probably should be a GUI tool for py2app that makes this a lot easier, but that's not going to happen anytime soon.

Subject: [Pythonmac-SIG] OSAscript from python doesn't trigger privileges
	prompt
Message-ID: <30380012.1372190732719.JavaMail.root@elwamui-muscovy.atl.sa.earthlink.net>

I'm writing a Python application that looks for a pkg file in a particular location, downloads it, and installs it.

Using osascript -e and Python's subprocess.Popen(), I can embed:

do shell script "sudo /usr/sbin/installer -pkg /path/to/file/filename.pkg -target /" with administrator privileges

When run interactively, this works fine. When the script hits the above line, it prompts me to enter my admin privileges and successfully runs installer.

When triggered by a launchd agent (in /Library/LaunchAgents/), the script runs and does everything except successfully install the package.

Any ideas what I'm doing wrong?

Thanks!
 Frank
