Hi all,
I am trying to port Krank python game to N900 but there are questions that I can't handle. Now I try to run the program on Ubuntu 8.04 and the errors
Code:
  File "/home/ubuntu/krank-07/src/Main.py", line 9, in <module>
    from World  import *
  File "/home/ubuntu/krank-07/src/World.py", line 8, in <module>
    from Level  import *
  File "/home/ubuntu/krank-07/src/Level.py", line 2, in <module>
    import k, levels
ImportError: No module named levels
In fact, there is already a __init__.py in "levels" folder. I want to google but can't find a proper solution as a python newbie. Can some python programmer help? Thanks.

regards,
pigling

Check your PYTHONPATH variable. It must include the directory in in which levels resides.

thanks for your kindly reply.
following is the folder structure:
Code:
krank-07/
    krank
    src/
        Main.py
        Level.py
    levels/
        __init__.py
original krank code as follow
Code:
#!/bin/sh
KRANKPATH=`dirname $0`
PYTHONPATH=$KRANKPATH:$PYTHONPATH
export PYTHONPATH
python $KRANKPATH/src/Main.py
now I change it to
Code:
#!/bin/sh
KRANKPATH=$( (cd -P $(dirname $0) && pwd) )
PYTHONPATH=/home/ubuntu/krank-07:/home/ubuntu/krank-07/levels
export PYTHONPATH
echo $PYTHONPATH
sudo nohup python $KRANKPATH/src/Main.py &
"sudo nohup python $KRANKPATH/src/Main.py &" is added because I want to see the log and make script run background otherwise the program will hang and I have to force quit.

I set PYTHONPATH to /home/ubuntu/krank-07 where Main.py stays. so you suggest to add /home/ubuntu/krank-07/levels in PYTHONPATH?

The following should work:

cd src
export PYTHONPATH=`pwd`:..
python Main.py

I.e. you should add krank-07 to your PYTHONPATH.

now I change it to
Code:
cd src
export = /home/ubuntu/krank-07:/home/ubuntu/krank-07/src:/home/krank-07/levels
python Main.py
above error solved. But new error happens
Code:
Traceback (most recent call last):
  File "Main.py", line 66, in <module>
    pygame.display.set_icon(pygame.image.load('levels/images/icon64x64.png'))
pygame.error: Couldn't open levels/images/icon64x64.png
I check that icon64x64.png exists. Is this a path issue or pygame library issue?

Just read the error messages. It doesn't find levels/images/... . So try moving to a path where it will find this file. Thus do

cd /home/ubuntu/krank-07
python src/Main.py

and the above path problem should go away.
