Error in launching GnuCash from terminal

[Rakesh]

Greetings:

I am GuCash in xfce 4.10, Debain Jessie, which performs normally when launched on desktop; but
Launching GnuCash from terminal reports an error: 

-------------------------------------------
rs at dhcppc0:~$ gnucash
Traceback (most recent call last):
  File "/usr/share/gnucash/python/init.py", line 3, in <module>
    from gnucash import *
ImportError: No module named gnucash
Found Finance::Quote version 1.38
Vector smash protection is enabled.
---------------------------------------------

I would be grateful for help /leads.
