Thanks to everyone for your helpful responses!
Пожалуйста
I can't compete with that. :)

Also see if Python shell and eric run the same Python (not 2.4

And try to work out, what's the difference between PYTHONPATHs and

Dou you have Eric (and dependencies) properly installed, by the
way? You know, .deb's from repositories, apt-get install and so on.
For here Eric picks up variables all right too.
Tusen takk.

Ha ha ha! My fault. It's actually Kubuntu 7.*, running KDE

Thank you for your response.
Yes, when running Python from the shell, the 'sys.path'
variable has
included the information in the 'PYTHONPATH' variable from the
shell.
Additionally, running the commands "os.environ['PYTHONPATH']" and
"os.system('echo $PYTHONPATH')" outputs the correct 'PYTHONPATH'
information.
However, it appears that Eric4 creates its own environment. The
'sys.path' variable does not include the 'PYTHONPATH'
information from
the shell in which Eric4 was started. Also, while the
"os.environ['PATH']" and "os.system( 'echo $PATH')" commands work
properly when run from Eric4, their values are different from the
'PATH' variable in the original shell. The
"os.environ['PYTHONPATH']"
and "os.system('echo $PYTHONPATH')" commands fail, indicating
that the
environment created by Eric4 is not the same as in the
original shell.
The above may be intentional, however I would like to be able
to do
one of the following:
1) Get Eric4 to inherit the PYTHONPATH information from the
shell in
which it is launched
2) Copy-paste the information from the PYTHONPATH variable into a
search path in the Eric4 project.
3) Run a short script at the beginning of my programs
something to the
effect of this:
newPaths = os.system( "Get PYTHONPATH info from
original shell" )
sys.path.append( newPaths )
Options 1) and 3) are preferable so that all the environment
info will
be picked up automatically.
If neither option is possible, I can manually insert the
search paths
using multiple "sys.path.append()" commands, but this will be a
maintenance headache and will be tougher to convince others to
move
away from print statement debugging. I am, of course, open to
other/better options.
Tusen takk.

Hello
I think you should learn about modules and their paths in
Python. For example, I don't know what is module gto,
probably it's your own one, and you rely on current dir
importing it... So read about PYTHONPATH and inspect its
value in your user shell, python and Eric shells
(sys.path), and remember about importing from current
directory.
Using Eric4 v4.2.3 (r2620) on KDE 7.
Whoops! Could you lend me your time machine? (-:E
I still haven't been able to figure this out.
More specifics, I'm importing a module named "gto" as
such:
import gto
This works fine if I run my python script from the
command line. When
I debug the script in Eric4 I get the following error
The debugged program raised the exception ImportError
"No module named gto"
So I'm wondering how I can get Eric4 to import the
environment from
the shell. Or at least how I can specify the paths in
which Eric4
will look for modules.

Thanks,

I'm trying to use Eric4 for python debugging in Linux
I'm having a problem with imported modules. These
modules are found somewhere in our system's path
variables (not sure where). The project I'm
trying to debug works fine when run from the
command line (and when debugged under pdb), but
Eric4 apparently doesn't pick up the environment
from the shell in which it was started, so an
error is thrown when attempting to import certain
modules.
I'm used to working on Visual Studio, so my first
instinct was to just copy the information from the
path variables into the the path variable in the
Eric4 project. I can't figure out how to do this.
Is there a way to get Eric4 to either pick up the
environment variables from the shell or to
transfer the path information so that Eric4 can
use it?
Using Eric4 v4.2.3 (r2620) on KDE 7.
Thank you.

Hi Robert,
Sorry to the list for my error on HTML precedent post :-(((
I discussed a bit with Detlev Offenbach concerning modules inclusion in
Eric4, due to a problem in
external classes declaration with Matplotlib ....
I think that we have a clear problem, simple to describe :
In Eric4, I declare :
from mplwidget import MyMplCanvas, Toolbar
or,
from mplwidget import *
Eric4 finds MyMplCanvas but complains that it "can't import name Toolbar ".
If I write the class Toolbar() in the main module .... it works,
Toolbar class is found, for sure ;-)
If I launch the program from command line : python the_program.py
....it works perfectly with either the first or second import declaration.
I conclude that Eric4 as a problem importing several classes declared in
an external module.
What do think about that, .... I did not experienced any problem with
PYTHONPATH, but I am using
the traditional /usr/lib/python tree ....
My config is Mandriva-2008-1:
Python 2.5.2
>From RiverBanks :
Qt 4.3.4
sip 4.7.7
QScintilla 2.3
eric4 4.2.4a(r2717)
Best regards,
Serge.
