FAQ
Hi all,

I recently downloaded and installed Python 2.3 for Windows (on XP
professional) and I don't seem to be able to run IDLE from my start
menu? It seems something happens when I click on it (ie I get an
hourglass) but no actual application turns up.

Has anyone else experienced this and can anyone give me some advice on
how to fix it?

Much warmth,

Murray

    Works for me, on Win2000. I've never used XP, but I'd suggest:

    *) opening a command-prompt box
    *) cd'ing to %PYTHON_HOME%\lib\idlelib
    (where PYTHON_HOME=C:\python23 unless changed at install time)
    *) ..\..\python idle.py

    watch out for error messages, and let us know...

    There are two known causes for this bug:

    -- you installed Python in a directory with a space in its path

    Workaround: uninstall it, install it again in a directory with
    no spaces in its path, e.g. its default C:\Python23

    -- you are running a "personal firewall" that is set to inhibit
    connections to host 127.0.0.1

    Workaround: remove your "personal firewall" or at least reprogram
    it so that connections to 127.0.0.1 are allowed; 127.0.0.1 in
    TCP/IP means "this very host, me, myself" and therefore there is
    no way in which connections to this address can put you at risk.

    IDLE 1.0 uses sockets for communication between the 'main' process
    and a secondary process that's set up to run code being developed,
    and some misprogrammed 'personal firewalls' are known to interfere
    with this. In theory, it is conceivable that a bad installation
    of "networking" on some Windows machine might cause the same
    effect as a misconfigured 'personal firewall', but so far in each
    case I've analyzed it did boil down to 'personal firewalls'.


    It's not necessarily the case that your troubles come from either
    of these known causes, but please check both of them -- if it's
    something else again, we'll need to root around for it.

    In addition to the two possible causes Alex spelled out, another common
    problem is some *other* program setting up Tcl or Tk environment variables
    pointing to an inappropriate version of Tcl/Tk. The installer for Ruby is
    the most common culprit for this problem, so if you've installed Ruby that's
    probably the cause.

    To check, open up a DOS box and try this:

    C:\Python23>python
    Python 2.3 (#46, Jul 29 2003, 09:29:04) [MSC v.1200 32 bit (Intel)] on win32
    Type "help", "copyright", "credits" or "license" for more information.
    import Tkinter
    Tkinter._test()

    I'm battling what seems to be a related issue on RH 9 (accursed Red Hat!). I
    installed 2.3 from src tarball last week, and it worked fine. The new Idle
    is very sexy. Yay, idle.

    Then last night I decided to upgrade from RH 8 to RH 9 (accursed Red Hat!).
    That was a disaster on many fronts (it's not a good thing to have corrup CD
    media on the 3rd disc of a KRUD update...argh!), but it also totally trashed
    my 2.3's _tkinter.so. Now when I try to rebuild 2.3 from src, I can't seem
    to get a _tkinter.so which points to valid tcl & tk libraries (despite using
    "--with-libs="" to point to the libtcl & libtk RH 9 installed).

    (The extent of my dynamic library fu on Linux is to futz around with
    symlinks from the places where _tkinter.so wants to find tcl/tk libs to the
    places where they actually are on my RH 9 (accursed Red Hat!) system, then
    to rerun /sbin/ldconfig. This "trick" didn't work either.)

    So I decided that RH is completely evil (accursed Red Hat!), and I would
    just install Tk & Tcl from scratch in /usr/local/lib and rebuild 2.3 using
    those libs, like this:

    ./configure --with-libs="/usr/local/lib/libtcl8.4.so \
    /usr/local/lib/libtk8.4.so"

    This works, but goddam what a pain in my ass...In case it's now clear by
    now: I hate Red Hat (though hitting back at SCO is pretty cool, trying to
    keep up with Python on a RH box has been way too painful for far too long).

    I recommend repeated playings, at max volume, of Bob Dylan's "Idiot Wind" if
    you have to fight this battle -- it seemed to help my mood.

    Hi Bernard,

    Well, yes, it seems there is a problem. Having followed your
    instructions, I get the following error(s):

    C:\Python23\Lib\idlelib>..\..\python idle.py
    Traceback (most recent call last):
    File "idle.py", line 23, in ?
    idlelib.PyShell.main()
    File "C:\Python23\lib\idlelib\PyShell.py", line 1264, in main
    root = Tk(className="Idle")
    File "C:\Python23\lib\lib-tk\Tkinter.py", line 1564, in __init__
    self.tk = _tkinter.create(screenName, baseName, className)
    _tkinter.TclError: Can't find a usable init.tcl in the following
    directories:

    files\ruby\tcl\lib\tcl8.3} {c:/program files/ruby/tcl/lib/tcl8.4}

    This probably means that Tcl wasn't installed properly.

    It appears the fact that I also have ruby installed is causing the
    problem? Should I uninstall ruby, do you think, and try re-installing
    python? I'd prefer to have access to both of them, but Python is the
    language I want to concentrate on at present.

    Thank you for your help!

    Much warmth,

    Do you have any form of "personal firewall" software? There is a known
    issue when Idle is used with a (misconfigured) firewall. The problem
    is that Idle relies on an internal socket connection. If the firewall
    is set to block that socket, Idle won't start. There should be no need
    to block traffic to IP address 127.0.0.1 (the local machine) so the
    firewall settings should be changed to allow this.

    For a better explanation, see http://www.python.org/2.3/bugs.html

    Hope this helps,
    Paul.

    I seem to recall ruby defines tcl/tk related environment variables
    which may interfere with python. If you are not using ruby-tk,
    I don't think you need to de-install but merely un-defining those
    variables should correct the situation. I think that's what I did
    long ago so I don't see those variable names myself, and can't
    be more specific....

    HTH,

    Bernard.

    Hi Bernard,

    Worked perfectly!

    Removed the ruby variables and now IDLE is running! Thank you to you
    (and also to the others that replied) for your help!
