Open Stack

Thanks Tony for reply
This is Jenkins third party.  So it is doing unstack and removing repo and stack again from master branch.  

It has been running OK and then it was disable for about a month.  Now when we reenabled it, it has this versionconflict one-by-one.  After I manually installed the required version for a lot of modules, it is OK now.  But I was just wondering why it won’t install the required package automatically instead of throwing exception?

You can look at our ci http://192.133.158.2:8080/job/cisco_zm_cinder/, look at all the failed cases yesterday.  I manually invoked pip install –c –e …   it will throw exception, is this really expected?  If it is not replace the modules with the required version, this kind of failure will happen again if somebody changed the requirement or constraints.

    You'll need to provide a little more information.  I'm assuming that you have a
    devstack setup that you're ./unstack,sh ; ./stack.sh to upgrade? and overtime
    the repos are gettiing out of sync.
    
    Can you explain what you're doing?
    
    Also can you please provide the out of:
    pip freeze | sort
    for repo in /opt/stack/* ; do (cd $repo ; [ -d .git ] && git describe ) ; done
    
    That will help us understand what you have and why the constratints file
    appears to be ineffective.
    
    Tony.
