Easy Install/setuptools installer for Python 2.6 on Windows
by Ray, Scott (SL) June 29, 2009

June 29, 2009

I recently installed Python 2.6.2 on MS Windows and would like to get Easy Install/setuptools working. The associated download page (http://pypi.python.org/pypi/setuptools) provides MS Windows .EXE installers for Python versions 2.3 - 2.5 only. Are there any prospects for a 2.6 installer? Or is there another reasonably straightforward way to get Easy Install/setuptools built and installed?

setup_requires not caching downloaded packages?
by Barry Warsaw June 28, 2009

June 28, 2009

We have a suite of tools in the 'lazr' namespace that we've begun to release as open source. All of these packages are maintained under bzr and it's really nice to be able to add this to our setup.py: setup_requires=['setuptools_bzr'] This extends setuptools so that we can use bzr instead of the built-in revision control systems. With that, 'python setup.py sdist' pulls in the right stuff. All of our packages are buildout based. The problem is that when we buildout the package, the download cache is never consulted and setuptools_bzr is /always/ downloaded. This is a non-starter for our production environments, which are not allowed to hit the external 'net during build time. Because of this, we've had to disable the setup_requires. We can kind of make things work with MANIFEST.ins but I'd prefer to be able to use setup_requires. Otherwise, um, what's the point of having this plugin? I'm not sure whether this is a bug in setuptools, distutils, or buildout, but since y'all are here, we should be able to figure it out. Or do you not think this is a bug? If you agree it's a bug, and we can agree where it's a bug, I'd be willing to put some time into fixing this, if we can get a timely update released in the affected package. Thanks, -Barry

newbie bootstrap question
by David Kim June 27, 2009

June 27, 2009

Sorry to ask, but I'm having with the first step of the buildout process, the bootstrap.py script. I get the following error: > Traceback (most recent call last): File "bootstrap.py", line 76, in <module> ws.find(pkg_resources.Requirement.parse('setuptools')).location AttributeError: 'NoneType' object has no attribute 'location' Unfortunately, I have no idea why this error is occurring. I am running on OS X Leopard and was just trying to bootstrap an empty buildout.cfg file to get things started. Tried googling the error, but nothing came up. Any pointers? -- morenotestoself.wordpress.com

Using setuptools as downloader for .msi/.exe
by Hartmut Goebel June 27, 2009

June 27, 2009

Hello, how can I use setuptools for downloading (and installing) .msi and .exe on Windows? I need this for extension modules like pygtk, lxml, psycopg2. Or at least for finding the files within a html page, like easy_install does. Background: The Tryton ERP system requires quite a lot of dependencies. The installation is an imposition to the user when following the installation instructions at <http://code.google.com/p/tryton/wiki/InstallationWindows>. So I want to write an installation script which bootstraps setuptools (this part is already done), installs requires eggs (done) and downloads .msi or .exe where eggs are not available. The later includes GTK+, Postgresql and some extension modules like pygtk. A normal Windows installer packages is not what I need here. The script is indented for a) developers who want to set up their own development environment and b) users who need to write extensions for their installation. Since the filenames may vary by version and python-version, (e.g. pygtk-2.12.1-1.win32-py2.5.exe) I do not want to hard-code these. Esp. since this would require changing the script quite often. easy_install already has a feature for finding the best-matching version -- Schönen Gruß - Regards Hartmut Goebel Dipl.-Informatiker (univ.), CISSP, CSSLP Goebel Consult Spezialist für IT-Sicherheit in komplexen Umgebungen http://www.goebel-consult.de

Why is zc.buildout picking the wrong platform for binary eggs?
by Martin Aspeli June 27, 2009

June 27, 2009

Hi, As some of you may know, using lxml on OSX is a big pain because of an incompatible system version of libxml2. The solution is to ship binary eggs, which we already do for Windows. Now, as a first test, Stefan has uploaded this egg: lxml-2.2.1-py2.4-macosx-10.5-i386.egg See http://pypi.python.org/pypi/lxml/2.2.1 Now, I'm on OSX 10.5, and I've requested this exact version. In a virtualenv, this works. It downloads the given binary egg. In a buildout, it's preferring to download and build the egg itself, and it calls it lxml-2.2.1-py2.4-macosx-10.3-i386.egg. That's weird, because this machine has never had OSX 10.3 on it. :( My Python 2.4.6 is installed via darwinports. Now, I can probably work around this, but we're trying to ensure that people have a sane lxml egg that will install cleanly on a number of platforms. It's therefore pretty important that the average user doesn't get this. So, I'd like to try and figure out what's going on. How does buildout decide which egg to look for? Why is easy_install in a virtualenv behaving differently to my buildout? Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.

Re: [Distutils] easy_install moinmoin does not work, (very) old url

This won't work. You may be successful by running: "easy_install http://static.moinmo.in/files/moin-1.8.4.tar.gz" The problem is that the package is mis-registered on PyPI; its setup.py declares its name "moin", so that is its distribution filename. However, on PyPI it is indexed as MoinMoin. You may wish to inform the maintainers of this, so they can update either the setup.py to use MoinMoin as the name, or change the Pypi registration to use "moin". Either should work, assuming that the distribution is able to work with setuptools. (You'll have to try it and see.)

SVN URLs in setuptools / EasyInstall?
by Mike Moerk June 24, 2009

June 24, 2009

I am trying to use setuptools and EasyInstall to handle dependency management for me, using a local subversion server. The svn server uses svnserve, not http. I have the following in my setup call: install_requires = ["myModule"], dependency_links = ["svn://myServer.myCompany.com/myModule"], But setuptools does not like the svn:// URL. I get the following error: Searching for myModule Reading svn://myServer.myCompany.com/myModule Download error: unknown url type: svn -- Some packages may not be found! I have also tried using find_links in the setup.cfg, rather than dependency_links in the setup.py. I get the same result. Here is my setup.cfg: [easy_install] allow_hosts = *.myCompany.com find_links = svn://myServer.myCompany.com/myModule The release notes for EasyInstall 0.3a2 say that download support was added for svn: URLs, which is what makes me think this is supposed to work. Is this a bug, or am I doing something wrong, or am I just misinterpreting what the tool can do?

Hello I've added Zip support for PEP 376, as asked by Ronald some time ago. I think I have included everything people reported in the code prototype and the PEP text, Any other feedback before I resend it back to python-dev, to propose its inclusion for 2.7/3.2 ? pep : http://svn.python.org/projects/peps/trunk/pep-0376.txt code prototype : http://bitbucket.org/tarek/pep376/src/tip/pkgutil.py Regards Tarek -- Tarek Ziadé | http://ziade.org

Autobuild packages using snakebite
by Leonardo Santagada June 20, 2009

June 20, 2009

I remember when snakebite was announced someone had the idea to have a kind of build bot go into pypi and get all packages sent to it and automatically compile them on snakebite for all major platforms and automatically run tests and submit the compiled packages to pypi. Is anyone working on this? The biggest problem I see is security, but if people are really interested in this we could at least try it no? Automatic testing in many python versions, conversion using 2to3 and building packages for windows and macosx seems like a very interesting service. -- Leonardo Santagada santagada at gmail.com
