Some issue with easy_install and PIL/Imaging

[KLEIN Stéphane]

Hi,

I would like to insert Imaging dependence in my setup.py file.

Resume :
1. first question : why PIL package in "pypi" don't work ?
2. second question : when I add PIL dependence in my setup.py and I do
    "python setup.py develop", I've this error :
    "error: Could not find required distribution Imaging".
    Why ?


Full explication :

First, I test manualy installation :

::

     (env1)sklein@eee-sklein:$ easy_install pil
     Searching for pil
     Reading http://pypi.python.org/simple/pil/
     Reading http://www.pythonware.com/products/pil
     Reading http://effbot.org/zone/pil-changes-115.htm
     Reading http://effbot.org/downloads/#Imaging
     No local packages or download links found for pil
     error: Could not find suitable distribution for
Requirement.parse('pil')

This command fail !

Now, I try with Imaging package name :

::

     (env1)sklein@eee-sklein:$ easy_install Imaging
     Searching for Imaging
     Reading http://pypi.python.org/simple/Imaging/
     Couldn't find index page for 'Imaging' (maybe misspelled?)
     Scanning index of all packages (this may take a while)
     Reading http://pypi.python.org/simple/
     No local packages or download links found for Imaging
     error: Could not find suitable distribution for
Requirement.parse('Imaging')

This command fail also.

Now, I add --find-links parameter to easy_install :

::

     (env1)sklein@eee-sklein:$ easy_install --find-links

This commend work but I have this error : "error: Could not find
required distribution Imaging". Why ?

Thanks for your help,
Stephane

See above.

If you google harder, you'll find there are packagings of PIL that do
work with setuptools...

It used to support this, but no longer does.  To me, that says more
about the state of setuptools than it does about the state of PIL,
which has been using the same naming convention for 15 years.

Ok, and what can we do ?

Is a setuptools issue ?

Can distribute (http://bitbucket.org/tarek/distribute/wiki/Home setuptools fork) fix this issue easily ?

Stephane

Yep, but it is now in the minority, and consistency in package naming is
always good.

Would there be any problems for you in naming the distribution in a
setuptools-friendly way from the next point release?

cheers,

Chris

The problem is that too many people arguing for eggs do this by
sending nastygrams, which doesn't really provide much motivation for
doing anything about it (I don't do asshole-driven development).  The
public review PIL got a couple a minutes ago matches some of the
private mail I've gotten:

   no egg - worst seen ever, remove it from pypi or provide an egg

Indeed, I couldn't agree more, and I'm sorry you've been subjected to this.

My (hopefully more polite) request still stands though:

*sigh*

Interesting timing, myself and Doug Hellmann have been trying to
persuade Martin von Lewis that while ratings are fine, the commenting
system is likely to be abused:

https://sourceforge.net/tracker/?func=detail&atid=513503&aid=2866081&group_id=66150
https://sourceforge.net/tracker/?func=detail&atid=513503&aid=2872293&group_id=66150

I'll put in a request to have that comment removed...

Chris
