Authentication via python?
by Benjamin Schollnick Aug. 21, 2009

Aug. 21, 2009

Folks, I¹m working on some time machine scripting... In a gist, there is a .Backup.log file that I want to access via readline & python.... >From the MOSX gui, it appears some of the files require root access (eg. Authentication dialog pops up). Now, I am using the applet maker to compile the python to a GUI stub, so I can¹t SUDO the python script... Is there some method that I can use to authenticate via the python script internally? I¹m in the middle of a google search on this, but I am having no luck at refining my search phrase currently (Macintosh python authenticate)... - Benjamin

(the one from python.org) If you are using an installer, then it has to be built for the python you want. Most only target one -- wxPython targets both python.org and Apple's (for Python 2.5) if you use easy_install or setup.py, be sure to run them with the python you want to use. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

py2app and ipython
by Thomas Robitaille April 30, 2009

April 30, 2009

Hi, I am trying to use py2app to make a simple MacOS X application that launches an ipython shell. At the moment, I have the following python script: --- from IPython.Shell import IPShellEmbed args = ['-pi1','In <\\#>:','-pi2',' .\\D.:','-po','Out<\\#>:','- nosep'] ipshell = IPShellEmbed(args, banner = 'Dropping into IPython', exit_msg = 'Leaving Interpreter, back to program.') ipshell() --- and the following setup.py file: --- from setuptools import setup setup( app=["test.py"], setup_requires=["py2app"], ) --- However, when I try launching the resulting executable, I get a dialog with "ImportError: No module named ipy_profile_none" What am I missing? Not sure if this is important, but when running setup.py py2app, I get the following warning: /usr/bin/strip: the __LINKEDIT segment does not cover the end of the file (can't be processed) in: /Users/tom/Code/python/experimental/ ipython/test/dist/aplpy.app/Contents/Frameworks/libgcc_s.1.dylib (for architecture i386) stripping saved 2585112 bytes (45897079 / 48482191) Thanks in advance for any advice, Thomas

Inside the package contents when I do a full build instead of an alias I see the following... /Users/elizabeth/Code/dist/mac_test.app/Contents/Resources/lib/python2.5/MySQLdb/ /Users/elizabeth/Code/dist/ mac_test.app/Contents/Resources/lib/python2.5/site-packages.zip I unzipped sites.packages.zip and found several .pyc files including _mysql.pyc and folders for the other module I'm importing (wx) Also when I try to build the whole app instead of the alias, using packages, I get "ImportModule error: No module MySQLdb" but when I use includes I receive the error "ImportError: '/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_mysql.so'" Is the Frameworks folder where my MySQLdb should be installed? because it's not there at all, it's in /Library/Python/2.5/site-packages and there is a _mysql.so in there.

py2app and mysqldb
by Elizabeth Lackey April 28, 2009

April 28, 2009

I am trying to use py2app to create my .app file, it gives me no errors, but I have MySQLdb installed properly, I can get to it from the python command prompt. My program works properly when I run it through Terminal, but obviously, that's not good enough for distribution. When I execute the .app created by py2app, I error out claiming the module is not imported. I cannot figure out the syntax to edit the setup.py file created by py2applet to allow for the MySQLdb module. I am fairly certain it's a syntax issue... but...I don't know what to do with the syntax. my current setup.py from setuptools import setup APP = ['mac_test.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], options=dict(py2app=dict(argv_emulation=True), ) ) I assume I need to add something along the lines of this, but I can't figure out the syntax options=dict(includes=['MySQLdb']) Please help!

App distribution with eggs
by David Woods April 27, 2009

April 27, 2009

I'm updating my development tools for an application I've been distributing for a few years now. One of my critical imports, MySQLdb, gets built as an egg under by new system. In the past, I've used BundleBuilder for making my distributable app for the Mac and it's worked admirably. I can't figure out how to get BundleBuilder to include the MySQLdb egg, (I get "ImportError: no module named MySQLdb") and it looks to me like py2app doesn't support eggs either. My (perhaps inept) Googling hasn't revealed any likely suspects. What method do folks recommend for building distributable apps which have dependencies on eggs? David

Re: [Pythonmac-SIG] Use Setup.py to install to /usr
by Pascal Schaedeli April 27, 2009

April 27, 2009

Thank you all on and off the list for your help and suggestions. I had tried to understand the meaning of http://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard for OS X, and your warnings clarified the difference between /usr and usr/local. Since duplicity is written to run under all Python >= 2.3, I attempted to make the installation non-version specific to ease Python upgrades. However, I hadn't realized that .pyc files were not backward compatible. So for now, duplicity is again installed in the version specific Python.framework directory. I sincerely appreciate your time helping me out. Thx again.

How to remove Python from my Mac?
by Ethan Herdrick April 25, 2009

April 25, 2009

Hi - I'm getting started with Python and am getting ImportError trouble with the first step of the very simple tutorial for web.py. I'm suspecting that the fact that I have two installations of Python - one that my Mac came with and one that I installed from python-2.6.2-macosx2009-04-16.dmg which I got from python.org/download/ - might be the problem. Also, in trying to get this thing going I was fiddling with the install_lib setting in .pydistutils.cfg and left it in a modified state before running setup.py on a module, so the module ended up in a strange location. Anyway, I'd really be happier if I could wipe all python stuff - including things like easy_install - from my machine so I can just start over. This seems to be harder than it sounds. True? And how do I do this? Thank you in advance.
