easy_install not working
by Andrea Crotti 25 Nov '11

25 Nov '11

Since some days easy_install doesn't work correctly anymore. I get for example something similar. Any idea of what it could be? In general setuptools is working perfectly, only easy_install is not working anymore.. [andrea@precision ~]$ easy_install-2.7 --user python-graph-core Traceback (most recent call last): File "/home/andrea/.local/bin/easy_install-2.7", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2711, in <module> parse_requirements(__requires__), Environment() File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 584, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: distribute==0.6.21

linking with libm
by Oscar Benjamin 23 Nov '11

23 Nov '11

Hello, I have an extension module that uses math.h. In order to compile it on Linux with gcc, it needs to link with libm. However, using libraries=['m'] leads to a linker error when using mingw32 on Windows. At the moment my setup.py contains something like: libraries = [] if not 'win' in sys.platform: libraries.append('m') This works for the two cases I user personally. I'm guessing, though, that I should really be checking for something more specific, perhaps to do with the compiler that is being used. I guess that using math.h and wanting cross-platform compilation is probably quite a common case. So I wondered if anyone who knows more than me about c-compilers and distutils has a better suggestion for this. Apologies if this is mentioned somewhere already. The only thing I could find in the docs was instructions for adding linker options when installing python modules. Ideally, I'd like to be able to handle this in my setup.py without needing the setup.py user to manually alter the linker settings. Thanks, Oscar.

[ANNOUNCE] pypiserver 0.4.0 - minimal pypi server
by Ralf Schmitt 21 Nov '11

21 Nov '11

Hi, I've just uploaded pypiserver 0.4.0 to the python package index. pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip. pypiserver is easy to install (i.e. just easy_install pypiserver). It doesn't have any external dependencies. http://pypi.python.org/pypi/pypiserver/ should contain enough information to easily get you started running your own PyPI server in a few minutes. The code is available on github: https://github.com/schmir/pypiserver Changes in version 0.4.0 ------------------------- - add functionality to manage package updates - updated documentation - python 3 support has been added -- Cheers, Ralf

setuptools-0.6c11.win32-py2.7.exe installation issue
by Ibon Net 18 Nov '11

18 Nov '11

Hi, trying to get lxml for my Python-on-Windows7, I ended up installing the setuptools. But when running it, the installer complains (after the first "Next" button) "Python version 2.7 required, which was not found in the registry". Pressing "Ok" presents a table headed by "Python 2.7 is required for this package. Select installation to use:" but the table is empty, and the two fields below for python and installation directories are read-only. Of course, I do have python installed - running "Python" will give my a console window running the interpreter which states "Python 2.7.2 (default, Jun 12 2011, 14:24:26) [MSC v.1500 64 bit (AMD64)] on win32" There are entries for .py files etc in the registry - but obviously not the ones the tool is looking for... What can I do? What more do you need to know? Regards, nobi -- http://www.fastmail.fm - A fast, anti-spam email service.

Need to install an unzipped version of an existing zipped package
by skip＠pobox.com 17 Nov '11

17 Nov '11

At work we have a package (MYSQL-python) which was mistakenly installed with easy_install as a zip archive. I'd like to reinstall as a non-zipped directory-based install. To guarantee that I get compile and link flags right I've been trying to experiment in my own site-packages directory but continue to be thwarted by the presence of the centrally installed zip archive version. For instance, if I execute this: export PYTHONPATH=$HOME/local/lib/python2.4/site-packages easy_install --prefix=$HOME/local -Z -U MYSQL-python it executes very quickly, with no obvious attempts to compile or link anything. When I look at the easy-install.pth file in my site-packages directory I find that all it did was drop in a reference to the centrally installed zip archive version of the package! That's not what I wanted at all. How can I tell easy_install to ignore that centrally installed version? Failing that, is it okay to simply unzip the package we have provided in the end it has the same name? Thanks, -- Skip Montanaro - skip(a)pobox.com - http://www.smontanaro.net/

Additional trove classifiers for Plone
by Alex Clark 15 Nov '11

15 Nov '11

Hi, The Plone project[1] has the need for additional trove classifiers to track add-on compatibility by version. Is something that could be added to: - http://pypi.python.org/pypi?%3Aaction=list_classifiers ? Or should we implement these internally?[2] Are there any repercussions in doing so? Thanks for any feedback. Alex [1] http://plone.org [2] https://github.com/collective/Products.PloneSoftwareCenter -- Alex Clark · http://aclark.net

More Re: Compatibility of bdist_rpm with Fedora packaging instructions
by Stanley A. Klein 12 Nov '11

12 Nov '11

Tarek - I realized that I needed to install distutils2 to run pypi2rpm, downloaded and installed a distutils2 rpm, and tried to build rpm packages of the systems I'm working on. I downloaded the pypi sdists of the packages and tried to run rpms of them. The source includes image files as well as Python code. I'm running into a problem where the image directories are failing to be packaged. They are included in the pypi sdists, but don't get into the rpms. Any ideas on how to get the image files into the rpm packages using distutils2 and pypi2rpm? Thanks.

Compatibility of bdist_rpm with Fedora packaging instructions
by Stanley A. Klein 10 Nov '11

10 Nov '11

I will need to build some Python packages for Fedora and Centos. The spec file produced by bdist_rpm automatically includes the statement %files -f INSTALLED_FILES The Fedora Python packaging instruction includes a recommendation to avoid use of INSTALLED_FILES and provides some alternatives. That is the first incompatibility I've encountered, but there may be more. The bdist_rpm code probably should be changed to enable compatibility. Meanwhile, is there a workaround? Stan Klein

make-like develop
by Andrea Crotti 07 Nov '11

07 Nov '11

Supposing that we have a directory with many eggs that compose our framework. All these eggs might (or might not be) used by applications that we write. So at the moment we run "python setup.py develop" on all of them. To avoid to waste too much time, however, the builder does a make-like operation, checking if "setup.py" was modified. So since I'm rewriting a new system to build/develop: - does it make sense to re-run develop when setup.py changes. And if yes are there other possible conditions which would force me to re-run it? - what could be a good way to implement a similar mechanism? Is there anything already I could use? I've seen watchdog (http://pypi.python.org/pypi/watchdog) which looks very interesting, and might be good to implement a service, but maybe it's overkill...
