Description of problem: https://www.openshift.com/forums/openshift/setuppy-installs-alembic-binary-in-wrong-python-environment My app's setup.py installs Alembic as a requirement, but the binary script is installed in wrong Python env during build phase (2.6 instead of 2.7): <code> (virtenv)[brewlog-zgoda.rhcloud.com 515a90de500446a7d6000007]\> cd $OPENSHIFT_REPO_DIR (virtenv)[brewlog-zgoda.rhcloud.com repo]\> alembic Traceback (most recent call last): File "/var/lib/openshift/515a90de500446a7d6000007/python/virtenv/bin/alembic", line 8, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in <module> working_set.require(__requires__) File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 648, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: alembic==0.5.0 </code> Package is installed properly, I can import it from Python shell. Now if i uninstall Alembic package by hand and then install it again using pip everything works fine and I can run alembic migrations. Am I doing something wrong or just spotted a bug?
