<p dir="ltr">I think it is indeed better to just use virtualenv in order to be safe. <br>
The error you are posting means that there is a corruption somehow on the python environment on your docker image maybe due to those force installs. I would start from scratch. Do you use a Dockerfile you can share?<br>

Thanks for the quick reply.<br>
<br>
We're running Buildbot in a Docker container. Will the --force-reinstall lead to an incoherent state for Buildbot? I'm not really concerned about other apps because Buildbot is the only thing we plan to run in the container.<br>
<br>
Will Virtualenv solve the seeming version conflict between SQLAlchemy and SQLAlchemy-Migrate versions (and what Buildbot needs?)<br>
<br>
I'm far from a Python guru so I'm not sure how to find what versions of these two packages will play nice with each other and support the needs of Buildbot other than trial and error. That seems like a pretty tedious adventure. ;)<br>
<br>
Right now I'm working in a 16.04 LTS based container so I can use current versions of these packages. I did not have this conflict with the older stuff ( 0.8.8 on Ubuntu 14.04) but it did not send email notification either.<br>
<br>
Thanks,<br>
hank<br>

<br>
Hi Hank,<br>
<br>
It is highly recommended to use virtualenv to install buildbot.<br>
Messing up with distro python packages with such options as --force-reinstall will lead to incoherent state and maybe instability of other distro programs.<br>

OS: Ubuntu 16.04 LTS<br>
Python 2.7.12<br>
Buildbot version: 0.8.12<br>
Twisted version: 16.0.0<br>
<br>
I'm confused. The manual at <a href="http://docs.buildbot.net/current/manual/installation.html#requirements" rel="noreferrer" target="_blank">http://docs.buildbot.net/current/manual/installation.html#requirements</a> (Says "Buildbot 0.8.12 documentation" at the top of the page) states:<br>
<br>
"Buildbot requires SQLAlchemy 0.6.0 or higher. SQLAlchemy allows Buildbot to build database schemas and queries for a wide variety of database systems."<br>
<br>
I have the default package for Ubuntu 16.04 installed:<br>
"ii python-sqlalchemy 1.0.11+ds1-1ubuntu2 all SQL toolkit and Object Relational Mapper for Python"<br>
(Looks like 1.0.11 to me.)<br>
<br>
A bit further on the same page I see:<br>
"Buildbot requires one of the following SQLAlchemy-Migrate versions: 0.7.1, 0.7.2 and 0.9. SQLAlchemy-Migrate-0.9 is required for compatibility with SQLAlchemy versions 0.8 and above. Buildbot uses SQLAlchemy-Migrate to manage schema upgrades from version to version."<br>
<br>
I install 0.9 using:<br>
"pip install -I sqlalchemy-migrate==0.9 --force-reinstall"<br>
<br>
When I run Buildbot it starts up but when it tries to send email, it gets an error:<br>

(Hmmm... package name is 1.0.11 and module identifies itself as 1.0.14 ...)<br>
<br>
What versions of these modules should I be running?<br>
<br>
