Wf is /etc/pythonstart? I don't have one. What does it say on and around line 7? import readline?

Note that python 3.1 code related to readline may be found in these files:
Code:
jameson@salmon:/usr/lib/python3.1$find . -name "*readline*"
./lib2to3/fixes/fix_xreadlines.py
./lib2to3/fixes/fix_xreadlines.pyc
./lib-dynload/readline.so
What do you see when you perform that find in your python dir?

Well in line 7 it says Import Readline. Funny thing is that it works perfectly in Red Hat Linux Enterprise 5. This is really getting into my nerve

Hi,

1) Temporarily add this line to your $HOME/.bashrc or $HOME/.profile:

Quote:
PYTHONPATH=$PYTHONPATH=/usr/lib/python3.1/lib-dynload/
export $PYTHONPATH
reset your shell and try to invoke python3.1

OR

2) Try to install first readline development headers (in Ubuntu called readline-dev; no idea how this is called, neither installed, in Suse) and then compiling Python 3.1 from source. [http://python.org]
This usually helps.


Hope this helps.

Thanks for your help but the above solution did not resolved my issue. It seems that the readline module was missing in SLES 11 which is important for Python 3 to run stable. Anyways i have resolved this issue and i would like to share the solution with you guys :-

Solution

1 - I downloaded readline 5.2 from icewalkers website
2 - Installed readline 5.2 by compiling it from the source code
3 - Re-compiled Python 3 from the source code
4 - I executed python 3 and everything is working smoothly without any error.
