ImportError: cannot import name patterns when access horizon using devstack

[juanjuan li]

I followed this link http://www.somsubhra.com/2017/03/30/devstack-openstack-test-environment-for-the-impatient/ to install devstack on my vm[x2go].
devstack works fine without cloudkitty.After enabling cloudkitty services, horizion shows some error.

Here is the error from horizion_error.log
root@jl044-KVM:/var/log/apache2# tail horizon_error.log

Here is how I set up local.conf
[[local|localrc]]
ADMIN_PASSWORD=admin
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

# ceilometer
enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer.git master

# horizon
enable_service horizon

# cloudkitty
enable_plugin cloudkitty https://git.openstack.org/openstack/cloudkitty.git master
enable_service ck-api ck-proc
CLOUDKITTY_COLLECTOR=ceilometer

I think the problem comes from the version of django. pattern has been deprecated since 1.8 and cloudkitty seems to still use version of 1.8.I have tried to change my latest django to the older version of 1.8, but there are some other errors pop up.

Does anyone can fix this problem?

Thanks
