tracspamfilter/Ubuntu16/trac109 - "VersionConflict: Python 2.7.11-

[Jimbo]

Hi, I've added tracspamfilter but see in /var/log/syslog:

svn Trac[loader] ERROR: Skipping "spamfilter.blogspam = tracspamfilter.filters.blogspam [json]": (version conflict "VersionConflict: (Python 2.7.11- (/usr/lib/python2.7/lib-dynload), Requirement.parse('python>=2.6'))")

Any help on this would be very gratefully received.

Ubuntu 16.04 LTS, installed from default repos trac 1.0.9, Python 2.7.11+

Tracspamfilter from https://trac.edgewall.org/browser/plugins/1.0/spam-filter?format=zip (builds TracSpamFilter-1.0.9.dev0-py2.7.egg)

Many thanks in advance.

It sounds similar to these issue:

https://trac.edgewall.org/ticket/12038

https://trac.edgewall.org/ticket/11993

However, the origin of the error looks different in these cases.

Which version of setuptools are you using or distribute are you using? Is it version >= 10?

How are you installing the package? Have you tried using pip?

It seems that python's version via pkg_resources is broken.
I consider that is a python2.7 ubuntu package issue.

Ubuntu 16.04:

Workaround is to remove json requirement from extra_requires in
spam-filter/setup.py:

I posted a possible workaround in:

[Jimbo]

Modifying setup.py as instructed seems to have worked.

Thanks all for the really fast help on this - it is very much appreciated.

If you wish to run unmodified code, and would like to confirm changes that were recently committed, you could try >= r14813.

The traceback I posted in (1) is probably related. I didn't find the issue reported in the Ubuntu issue tracker (2). I wonder if we should report this so that hopefully it gets fixed and we don't have to find a workaround.

Ryan, thanks, R14815 looks to be OK.

Incidentally "sudo easy_install TracSpamFilter" doesn't work currently as it looks that the module isn't available (the folder is empty) - is this by design? Perhaps something for a different message list.

The plugin needs to be uploaded to PyPI, but none of the current maintainers have permission to do so, and I haven't been able to get in touch with the original author. I added some comments about that in:

https://trac.edgewall.org/ticket/12270

I'll make another attempt to get in touch with the original author to see if he can grant us permissions.
