can not reproduce this bug on my environment, could you run 'tox -r -e genconfig' again to check?

[Shaoman Zhang (zhang-shaoman)]

Use 'tox -r -e genconfig', get the same error. :(

[gordon chung (chungg)]

what version of wsme do you have?

[Shaoman Zhang (zhang-shaoman)]

wsme version is 0.6.1

[gordon chung (chungg)]

I'll need to check with dhellmann... This issue is only fixed in 0.8.0

[gordon chung (chungg)]

what version of tox and pbr do you have?

[gordon chung (chungg)]

hmm.. it didn't pick up my comment... but this passes fine in gate.

[Shaoman Zhang (zhang-shaoman)]

tox version is 1.8.1, pbr version is 0.11.0

[gordon chung (chungg)]

can you try with a newer build of tox? say tox==2.1?

[ZhiQiang Fan (aji-zqfan)]

in a clean new env, cannot reproduce this issue, I think it is related to your environment
sometimes when we checkout branch from master to stable/xxx, the remain old file of *.pyc may have some side effect, for example, I have come across "AttributeError: 'module' object has no attribute 'monkey_patch'" once just because the pyc files exist in master branch pollute the stable/kilo branch.

[Shaoman Zhang (zhang-shaoman)]

change wsme from 0.6.1 to 0.8.0, generate ceilometer.conf successfully.
so the question is wsme version requirement is not right?
