Hello,
I have installed A2billing 1.4 on debian. I have also installed the callback daemon by following the setup instruction given by the a2billing team.
When I try to start the callback daemon with the command: service a2b-callback-daemon start, I get the following error message:
srva13:/usr/src/a2b-1.4/CallBack/callback-daemon-py/callback_daemon# service a2b-callback-daemon start Starting a2b-callback-daemon : a2b-callback-daemon:Traceback (most recent call last): File "/usr/bin/a2b_callback_daemon", line 7, in ? sys.exit( File "/usr/lib/python2.4/site-packages/pkg_resources.py", line 236, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.4/site-packages/pkg_resources.py", line 2097, in load_entry_point return ep.load() File "/usr/lib/python2.4/site-packages/pkg_resources.py", line 1830, in load entry = __import__(self.module_name, globals(),globals(), ['__name__']) File "build/bdist.linux-x86_64/egg/callback_daemon/a2b_callback_daemon.py", line 23, in ? File "build/bdist.linux-x86_64/egg/callback_daemon/database.py", line 28, in ? ImportError: cannot import name sessionmaker failed!
Please help me fixing this problem.
Thanks.
