Hello,

I am an EMACS user and I know scheme, but I don't know EMACS lisp and I've run
into a problem where I could use some help.

I installed the following packages on Ubuntu intrepid:

bash$ dpkg -l | grep -E 'emacs|python-mode'
ii  emacs                                      22.2-0ubuntu2                               The GNU Emacs editor (metapackage)
ii  emacs22-bin-common                         22.2-0ubuntu2                               The GNU Emacs editor's shared, architecture
ii  emacs22-common                             22.2-0ubuntu2                               The GNU Emacs editor's common infrastructure
ii  emacs22-gtk                                22.2-0ubuntu2                               The GNU Emacs editor (with GTK+ 2.x support)
ii  emacsen-common                             1.4.17                                      Common facilities for all emacsen
ii  python-mode                                1:1.0-3.1ubuntu4                            Emacs-lisp python-mode and doctest-mode for

When I go to edit a python file with emacs, I get this in my messages buffer:

("emacs" "/tmp/foo.py")

(New file)
File mode specification error: (file-error "Cannot open load file" "python-mode")

When I run M-x python-mode, I get this message:

call-interactively: Cannot open load file: python-mode

And yet, it appears to be there:

bash$ locate python-mode
/etc/emacs/site-start.d/50python-mode.el
/usr/lib/emacsen-common/packages/install/python-mode
/usr/lib/emacsen-common/packages/remove/python-mode

Can anyone please help me figure out how to troubleshoot this?

BTW: Thanks for creating such a wonderful editor!  It has really helped me
as a programmer over the years.

Launch GNU Emacs with -q and check the value of the variable load- 
path. When it does not contain the element /usr/share/emacs/site-lisp/ 
python-mode then you'll need to add it, because GNU Emacs searches in  
the directories given by load-path for .EL or .ELC files. You can do  
it like this in your init file (which won't make the error from /etc/ 
emacs/site-start.d/50python-mode.el go away):

	(add-to-list 'load-path "/usr/share/emacs/site-lisp/python-mode")

If this element is contained in load-path, then the syntax to load  
that file is obviously faulty. The error message cites "Cannot open  
load file" so it seems that the function load-file is used, which  
assumes that the given file is complete, i.e., its extension is  
named. The correct function call should be load-library. If the  
latter is used *and* /usr/share/emacs/site-lisp/python-mode is in  
load-path then the variables load-suffixes and load-file-rep-suffixes  
could be wrong. The former should contain el and elc, the latter gz  
to enable a modern GNU Emacs to load gzip'ed ELisp files.

Interactively you could try:

	M-x load-library RET python-mode RET


The file python-mode.el seems to be an XEmacs file. GNU Emacs comes  
with python.el. I think its "loaded" into GNU Emacs. The variable  
auto-mode-alist should contain a mapping from .py files to python- 
mode. So there should be no need for a python-mode.el file. Maybe  
you'll have more success when you remove the python-mode package  
(which should be easy).
