</div>
The problem seems to be when we pip install -e oslo.config on the system, then pip install oslo.sphinx in a venv. oslo.config is unavailable in the venv, apparently because the namespace package for o.s causes the egg-link for o.c to be ignored. Pretty much every other combination I've tried (regular pip install of both, or pip install -e of both, regardless of where they are) works fine, but there seem to be other issues with all of the other options we've explored so far.<br>
<br> We can't remove the pip install -e of oslo.config because it has to be used for gating, and we can't pip install -e oslo.sphinx because it's not a runtime dep so it doesn't belong in the gate. Changing the toplevel package for oslo.sphinx was also mentioned, but has obvious drawbacks too.<br>
<br> I think that about covers what I know so far.</blockquote>

<div>This just bit me again trying to run unit tests against a fresh Nova tree. I don't think it's just me either - Matt Riedemann said he has been disabling site-packages in tox.ini for local tox runs. We really need to do _something_ about this, even if it's just disabling site-packages by default in tox.ini for the affected projects. A different option would be nice, but based on our previous discussion I'm not sure we're going to find one.</div>

<div style="font-size:small">Is the problem isolated to oslo.sphinx? That is, do we end up with any configurations where we have 2 oslo libraries installed in different modes (development and "regular") where one of those 2 libraries is not oslo.sphinx? Because if the issue is really just oslo.sphinx, we can rename that to move it out of the namespace package.</div>

<div style="font-size:small">oslo.sphinx is the only one that has triggered this for me so far. I think it's less likely to happen with the others because they tend to be runtime dependencies so they get installed in devstack, whereas oslo.sphinx doesn't because it's a build dep (AIUI anyway).</div>
