[Eric] Re: Question about imported modules and paths in Eric4

[Robert Cheatham]

Ha ha ha!  My fault.  It's actually Kubuntu 7.*, running KDE 3.5.6.
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.

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.

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 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?
