Verify Keystone with Curl

I'm a newcomer in Openstack

I tried to install keystone with "apt-get install keystone"

After installation, I modified the keystone.conf listed later

I typed "curl http://0.0.0.0:35357" to verify the installation, but I got the message as following:

{"IdentityFault": {"message": "Unhandled error", "code": "500", "details": "Template u'/usr/keystone/content/admin/version.json.tpl' not found at line 0 column 0"}}

Did I config something wrong ? How can I solve this problem?
