plone - Version conflict when using buildout.plonetest 4.3.x -

-

i wrote small module extends https://raw.github.com/collective/buildout.plonetest/master/test-4.2.x.cfg. if change version 4.2 4.3 throws error when running bin/buildout:

... while:   installing.   getting section test.   initializing section test.   installing recipe zc.recipe.testrunner. error: there version conflict. have: zc.recipe.egg 2.0.0

i suppose error produced because packages listed in buildout.plonetest have conflicting versions , bug in 4.3 version set. i'm right or i'm making mistake in buildout.cfg file?

the buildout i'm using is:

[buildout] extends =     https://raw.github.com/collective/buildout.plonetest/master/test-4.2.x.cfg package-name = conaride.theme package-extras = [test]  [instance] eggs +=     pillow  [test] defaults = ['-s', '${buildout:package-name}', '--auto-color', '--auto-progress']

there no bug in 4.3 version set; need fix version conflict. try or of following approaches very-common problem:

(1) remove already-downloaded version , re-run buildout e.g.:

$ rm -rf eggs/zc.recipe.egg\* $ bin/buildout

(2) remove installed config , re-run buildout e.g.:

$ rm .installed.cfg $ bin/buildout

(3) specify version want use in local config e.g.

[versions] zc.recipe.egg = 2.0.0
