Juno keystone installation fail to import oslo_i18n

[xugangsh]

Test keystone installation on stable/juno recently, but failed to import module oslo_i18n

I checked global requirements for stable/juno
http://git.openstack.org/cgit/openstack/requirements/tree/global-requirements.txt?h=stable/juno

I found oslo.utils is below
oslo.utils>=1.4.0,<1.5.0 # Apache-2.0

But oslo.i18n still below
oslo.i18n>=1.0.0,<=1.3.1 # Apache-2.0

And from requirements of oslo.utils 1.4.0
http://git.openstack.org/cgit/openstack/oslo.utils/tree/requirements.txt?id=1.4.0

If we install oslo.utils version 1.4.0, it will require oslo.i18n >= 1.3.0
oslo.i18n>=1.3.0 # Apache-2.0

So if we only install oslo.i18n 1.0.0, it will output can not find module oslo_i18n

[Steve Martinelli (stevemar)]

was this done with devstack or a particular distribution?

[xugangsh (xugangsh)]

We used some scripts similar to devstack but distro like RDO epel repo
All are rpms.
The command is like below

yum install openstack-keystone python-keystoneclient

They will automatically pull oslo.utils with 1.4.0 and oslo.i18n 1.0.0 which is minimum version of Juno

After I upgrade oslo.i18n to 1.3.0, then keystone installation can pass

Moved this to oslo.i18n, but it sounds like openstack/requirements for stable/juno just need to be fixed to reflect the reality (that oslo.utils 1.4.0 requires oslo.i18n>=1.3.0).

[Dolph Mathews (dolph)]

Fixed proposed to openstack/requirements:

(If there's an LP project to track bugs in openstack/requirements, please move this bug! Thanks.)

per comment 3,

Yeah, in fact, I would open bug to requirements category which I did not find.
