Public bug reported: I am running Mailman 3 in a virtualenv with most of its package dependencies installed through pip. In this particular configuration, if I run `buildout`, the test script that is created cannot seem to load zope.testrunner properly: $ bin/test -vv Traceback (most recent call last): File "bin/test", line 35, in <module> import zope.testrunner ImportError: No module named testrunner The workaround is to remove the eggs folder, pip install zope.testrunner, and then re-run buildout. ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/869347 Title: bin/test script fails unless zope.testrunner is pip installed To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/869347/+subscriptions
