Hi, Everyone: When I am using TripleO to build an undercloud image, it will install packages in /opt/stack/venvs/openstack. But SqlAlchemy version in /opt/stack/venvs/openstack/lib is 0.7, but SqlAchemy in /user/lib/ is 0.8, how can fix this? Why is Sqlalchemy version in venvs lower than /user/lib ? How can control package version when building undercloud image? Thank you for any help in advance. *Best Regards!* *Chao Yan--------------**My twitter:Andy Yan @yanchao727 <https://twitter.com/yanchao727>* *My Weibo:http://weibo.com/herewearenow <http://weibo.com/herewearenow>--------------* -------------- next part -------------- An HTML attachment was scrubbed...
