ImportError: No module named scheduler

[peter.h...@gmail.com]

Hello,

I am installing vFense server on an Ubuntu 12.04.4. Everything goed well until I want to start the vFense server with the following command:

sudo python /opt/TopPatch/tp/src/daemon/vFensed start

Result is that I am getting the following traceback:
Traceback (most recent call last):
  File "src/vFense_listener.py", line 30, in <module>
    from vFense.scheduler.jobManager import start_scheduler
  File "/usr/local/lib/python2.7/dist-packages/vFense/scheduler/jobManager.py", line 8, in <module>
      File "src/vFense_listener.py", line 30, in <module>
    from apscheduler.scheduler import Scheduler
ImportErrorfrom vFense.scheduler.jobManager import start_scheduler
  File "/usr/local/lib/python2.7/dist-packages/vFense/scheduler/jobManager.py", line 8, in <module>
    : No module named scheduler
from apscheduler.scheduler import Scheduler
ImportError: No module named scheduler

The apscheduler is installed:

sudo pip install apscheduler
Requirement already satisfied (use --upgrade to upgrade): apscheduler in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): six in /usr/local/lib/python2.7/dist-packages (from apscheduler)
Requirement already satisfied (use --upgrade to upgrade): pytz in /usr/local/lib/python2.7/dist-packages (from apscheduler)
Requirement already satisfied (use --upgrade to upgrade): tzlocal in /usr/local/lib/python2.7/dist-packages (from apscheduler)
Requirement already satisfied (use --upgrade to upgrade): futures in /usr/local/lib/python2.7/dist-packages (from apscheduler)
Cleaning up...

Running the --upgrade as suggested does not solve the problem.

What could be the issue here?
