python pyjamas install on debian

i have installed pyjamas on debian

http://pyjs.org/getting_started.html

however my program does not find the module, what could be the problem, i have installed pyjamas correctly using apt-get

krisdigitx-virtual-machine ~ # python jamas.py 
Traceback (most recent call last):
  File "jamas.py", line 3, in <module>
    from pyjamas import Window
ImportError: No module named pyjamas
krisdigitx-virtual-machine ~ # 


#!/usr/bin/env python

from pyjs import Window
from pyjs.ui import RootPanel, Button
from pyjs.ui import HTML


def greet(sender):
    Window.alert("Hello Krishna!")

b = Button("click me", greet)
Rootpanel().add(b)

After some research:

i had开发者_运维百科 to do pyjsbuild jamas.py to get the output directory, however it gives me a new error

jamas TypeError: jamas.RootPanel().add is not a function

Since you get an

ImportError: No module named pyjamas

you may need to add the module's path to $PYTHONPATH with

export PYTHONPATH=$PYTHONPATH:/usr/share/pyjamas/library

1. Please go to http://pyjs.org/GettingHelp.html
2. The first link "Getting Started" is a detailled walkthrough for an installation to start from scratch. Basically, what it says there is: Get the up-to-date source code from the git repository.

All steps to get Pyjs and Pyjs Desktop running are described in the Wiki article in the necessary detail, but still concise enough.
