spyder doesn't have PYTHONPATH when run from the Dash

[KrisThielemans]

we set PYTHONPATH via .bashrc but this is ignored when directly launching it from the "Activities" centre

[paskino]

I've added the PYTHONPATH variable to the spyder interface. However, that's not sufficient to run the software because all the other environment variables are needed.

Known problem, see https://lwn.net/Articles/709769/
Recently fixed https://bugzilla.gnome.org/show_bug.cgi?id=736660 by adding the following to /usr/bin/gnome-session at the start

if [ "x$XDG_SESSION_TYPE" = "xwayland" ] &&
   [ "x$XDG_SESSION_CLASS" != "xgreeter" ] &&
   [  -n "$SHELL" ] &&
   grep -q "$SHELL" /etc/shells &&
   ! (echo "$SHELL" | grep -q "false") &&
   ! (echo "$SHELL" | grep -q "nologin"); then
  if [ "$1" != '-l' ]; then
    exec bash -c "exec -l '$SHELL' -c '$0 -l $*'"
  else
    shift
  fi
fi

we should do this (with a note to check when upgrading to a later ubuntu...).
Or does a "apt-get upgrade" already fix this?

Just tried to add the code in the /usr/bin/gnome-session and start spyder from the Activities and got the ImportError: No module named pSTIR meaning that the trick doesn't seem to work.

[KrisThielemans]

ok. let's postpone this then. I'll reassign to v1.1

Have you actually tried to export in the ~/.profile. That is the proper file for this usage.
Before seeing the changes logout.

[NikEfth]

In addition, appropriate would be a .sh in the /etc/profile.d/ if it needs to be system-wide

[KrisThielemans]

~/.profile is a good idea. /etc/profile.d/ is probably overkill in a VM with a single user.

but it is set in /home/sirfuser/devel/install/bin/env_ccppetmr.sh
which is sourced from ~/.sirfrc
which is sourced from ./bashrc

I think it is wrong because the value of $PYTHONPATH ends with a trailing ':' possibly due to it being created by pre-pending to an unset variable:
PYTHONPATH=/home/sirfuser/devel/install/python:$PYTHONPATH

[casperdcl]

clearly dash doesn't source .bashrc then. But this should be fixed when we switch to setup.py and/or conda.

[KrisThielemans]

just a reminder that spyder should be ok when run from the command line

[KrisThielemans]

This would be resolved once we use setup.py as opposed to PYTHONPATH. Therefore postponing
