But the jsonRpcUtils was in tests path. How about move it to yajson or some other package. Now, if I want to import TestClientWrapper from this module, I should set the PYTHONPATH=/usr/share/vdsm/tests/ And without setting PYTHONPATH, I have added a __init__.py in my patch to make the /usr/share/vdsm/tests/ as a python sitelib. http://gerrit.ovirt.org/#/c/11283/ -- Sheldon Feng(冯少合)shao...@linux.vnet.ibm.com IBM Linux Technology Center ___ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel
