Hi all, I've been aware that the distutils sig has been simmerring away, but until recently it has not been directly relevant to what I do. I like the look of the proposed api, but have one question. Will this support an installed system that has multiple versions of the same package installed simultaneously? If not, then this would seem to be a significant limitation, especially when dependencies between packages are considered. Assuming it does, then how will this be achieved? I am presently managing this with a messy arrangement of symlinks. A package is installed with its version number in it's name, and a separate directory is created for an application with links from the unversioned package name to the versioned one. Then I just set the pythonpath to this directory. A sample of what the directory looks like is shown below. I'm sure there is a better solution that this, and I'm not sure that this would work under windows anyway (does windows have symlinks?). So, has this SIG considered such versioning issues yet?

eggs and Python Unicode variants (UCS2, UCS4)

by Martijn Faassen

Hi there, In the lxml project (http://codespeak.net/lxml), we've just noticed the following problem with lxml eggs: you can easy_install an egg that won't work for your Python. This is because Python can be compiled with either 2 or 4 bytes unicode as its internal representation. Any egg that contains compiled C code that uses unicode such as lxml will run into trouble: if it's compiled with a 4 bytes unicode Python, it won't work on a 2 bytes unicode Python, and vice versa. This problem is fairly common in Linux. Many distributions such as Ubuntu and Fedora compile their python with 4 bytes unicode internal representation. If you compile a Python interpreter by hand it defaults to 2 bytes unicode, however. Hand-building a Python interpreter is done fairly commonly by Linux sysadmins for various reasons. It would therefore be very nice if it became possible to make eggs for the different unicode compilation options of Python. This configuration dimension is a real world issue for any binary Python module that does anything with unicode text.. In an earlier mail to this list: http://mail.python.org/pipermail/distutils-sig/2005-October/005222.html M.-A. Lemburg and Phillip Eby had the following discussion: [MAL] >>Please make sure that your eggs catch all possible >>Python binary build dimensions: >> >>* Python version >>* Python Unicode variant (UCS2, UCS4) >>* OS name >>* OS version >>* Platform architecture (e.g. 32-bit vs. 64-bit) [PJE] >As far as I know, all of this except the Unicode variant is captured in >distutils' get_platform(). And if it's not, it should be, since it >affects any other kind of bdist mechanism. I'm not sure whether this means this needs to be escalated from setuptools to the Python interpreter level itself. With this mail, I've done the job escalating this lxml problem to what appears to be the right place, though. :) Thanks, Martijn

setuptools site-package pollution

by Anthony Tarlano

Hi all.. Firstly, I would like to say thanks for the setuptools package, which I was introduced to after reading about the RuleDispatch package on the IBM developerworks charming python series. Oh btw. RuleDispatch is the most useful python package that I have seen in the last year in the python world, so thanks for that also ;) Now that the congrats and hugs are out of the way, I would like to ask a question. How can I tell setuptools not to put packages, such as dispatch, protocols, and setuptools, in a subdirectory named the same as the egg and to just put the package name. For example from pydoc I currently get: c:\python\lib\site-packages\ruledispatch-0.5a0.dev_r2100-py2.4-win32.egg dispatch (package) c:\python\lib\site-packages\pyprotocols-1.0a0dev_r2082-py2.4-win32.egg dispatch protocols (package) c:\python\lib\site-packages\setuptools-0.6a8-py2.4.egg easy_install pkg_resources setuptools (package) site what I would like to see is just: ..\site-packages dispatch (package) ..\site-packages protocols (package) ..\site-packages setuptools (package) Maybe it is just a pet-peeve, but I like to keep a nice tidy site-packages directory, and these long directory names just seem to me to be pollution of my site-packages directory in my command shell. If there is an option to have just the packages, I would really appreciate someone telling me what it is. If not maybe it could be considered, and to put whatever meta-data the directory names are providing somewhere else.. Thanks, Anthony

Please install >a more recent version first. Ah, the plot thickens. This error message only occurs if there is a version *conflict* error - that is, you have an installed version of setuptools on your sys.path that is a lower version than 0.6a11. This could happen if your default installation location is later on sys.path than the installation location for an older version of setuptools. Try this: % python2.4 >>> import pkg_resources >>> print list(pkg_resources.working_set) And send me the output. I'm guessing it will show a version of setuptools that's less than 0.6a11, and the path shown with it will be different than the one you've been installing later versions of setuptools to. (Oh, and also check which Python version is being run by your easy_install script, to make sure you run the same version to do the above.)

That problem is due to them using a11 after I killed off all the alpha releases from the Cheeseshop to keep people from installing versions that had some rather serious bugs that were fixed by the beta versions. This doesn't affect your problem; even though they've changed the ez_setup you're still going to get an installation conflict error in your installation. The problem you're having is specific to your installation, in other words. On the whole, I think ez_setup is going to have to grow a way to bootstrap to the "latest non-alpha version" if there's one out there. I should probably also have it output information about the conflicting setuptools installation if there's a conflict, as that would have made your problem easier for you to spot up front. >Hamish >_______________________________________________ >Distutils-SIG maillist - Distutils-SIG(a)python.org >http://mail.python.org/mailman/listinfo/distutils-sig

Spurious "required version not available" error for setuptools?

Others on the Kid mailing list seem to be having setuptools problems: <http://sourceforge.net/mailarchive/forum.php?thread_id=30391159&forum_id=43…> Is it Kid's installation setup that's awry? Hamish

Well, try "easy_install -U setuptools"; it's possible your current installation isn't actually 0.6c1. (If you're on Windows, use "ez_setup.py -U setuptools" instead).
