[ckan-dev] nosetests conflicting version requirements

Mon Oct 28 13:59:23 UTC 2013

Hello there,

I am now stuck for a while on an error I receive when I try to test my
CKAN extension [1].

/home/konrad/pyenv/lib/python2.7/site-packages/nose/plugins/manager.py:395:
RuntimeWarning: Unable to load plugin pylons = pylons.test:PylonsPlugin:
(WebOb 1.0.8 (/home/konrad/pyenv/lib/python2.7/site-packages),
Requirement.parse('WebOb>=1.2'))
  RuntimeWarning)

The Python packages are all installed as specified in the requirement
text files. Especially, I am on:

nose==1.3.0
Pylons==0.9.7
WebOb==1.0.8

I cannot resolve this error, because CKAN requires WebOb 1.0.8 due to
deprecation of UnicodeMultiDict. I cannot update Pylons either, because
then it will not work, too.

The error only appears if the test involves ckan or ckanext-harvest
modules. Any idea how to proceed here?

Best,
Konrad
