Not installing the install_requires
I've just made a package http://pypi.python.org/pypi/premailer To figure out if I've got it right I've tried installing it like this:: $ cd /tmp $ mkvirtualenv --no-site-packages test_premailer $ easy_install premailer Searching for premailer Reading http://pypi.python.org/simple/premailer/ Page at http://pypi.python.org/simple/premailer/ links to .py file(s) without version info; an index scan is required.

Because it has to evaluate your setup.py to learn that it requires lxml, but your setup.py *also* requires lxml, apparently because you're trying to avoid spelling our your package's version number more than once. This has been discussed recently on this list a couple times: http://mail.python.org/pipermail/distutils-sig/2009-May/011913.html http://mail.python.org/pipermail/distutils-sig/2009-July/012441.html The gist is that there is no way to declare things which your setup.py depends on, so if you depend on anything novel in it, it will probably fail like this for someone.

(djangopeoplenet)peterbe@trillian:~/djangopeoplenet $ easy_install
Ok. Thanks for spotting that. I'll change the package so that I manually type in the version number. Or even better actually. I'll add a file into the package called version.txt and read that on the fly. I've got a more pressing problem now, when I try to easy_install my package it tries to install lxml even though it's already installed!

Getting lxml to build in a virtual environment is far from trivial and that's why I (amongst others) prefer to use OS packages (debian apt in my case).
Crap! That didn't work either! IOError: [Errno 20] Not a directory: '/home/peterbe/virtualenvs/ djangopeoplenet/lib/python2.5/site-packages/premailer-1.2-py2.5.egg/ premailer/version.txt' This must be because of some egg magic that I don't understand. What I did was this (in premailer.py): __version__ = open(os.path.join(os.path.dirname(__file__), 'version.txt') ).read().strip() That works if the thing is installed. But not when trying to use it as an egg. I tried to read P.J Eby's reply regarding using execfile() but it went over my head. On Jul 15, 2:16 pm, Jean-Paul Calderone <exar...@divmod.com> wrote:
