Swift upgrade issue - 1.9.0 to 1.10.0


We are trying to upgrade swift 1.9.0 to 1.10.0.

The ubuntu OS is 13.10. After the upgrade, all the features are working fine. Except, swift-ring-builder command which give below error :

root@swift-proxy-2:~# swift-ring-builder /etc/swift/account.builder Traceback (most recent call last): File "/usr/local/bin/swift-ring-builder", line 31, in <module> from swift.common.ring.utils import parse_search_value, parse_args, \ ImportError: cannot import name parse_args

We have upgraded it using the tar.gz available at The upgrade steps included :

1) stop all the relevant swift services, python install command and then start services.

Above was done first on storage nodes followed by proxy server.

Any help would be appreciated.
