Hi Tom,
Thanks for helping me. I looked into runner.py and this is what I see:
# we need to import python modules from the $SUMO_HOME/tools directory
try:
sys.path.append(os.path.join(os.path.dirname(
__file__), '..', '..', '..', '..', "tools")) # tutorial in tests
sys.path.append(os.path.join(os.environ.get("SUMO_HOME", os.path.join(
os.path.dirname(__file__), "..", "..", "..")), "tools")) # tutorial in
docs
from sumolib import checkBinary
except ImportError:
sys.exit(
“please declare environment variable 'SUMO_HOME' as the root directory
of your sumo installation (it should contain folders 'bin', 'tools' and
'docs')")
Yes, the “sys.path.append” lines (and their continuation lines) need to be
commented-out.
My original explanation claimed that the first line was already commented-out,
but that was because I’ve been tracking down other edge-cases and in my test
build it already was. Not for you though.
In this case you need to retain the “from sumo lib import checkBinary” but get
rid of the other two sys.path.append lines.
The next problem you will have is that /opt/local/share/doc/sumo is not open
for writing, and this test program wants to open ./data/cross.rou.xml as output.
If you copy the directory and contents to your own directory:
cd ~
cp -r /opt/local/share/doc/sumo/tutorials/traci_tls .
cd traci_tls
./runner.py
then (if those lines are commented out) it should run for you (it does for me).
btw, if you specify “python runner.py” then you need to make sure that it is
python2.7 which is what the SUMO port uses.
I’m preparing patches for the port file which will fix this and a few other
issues but it will likely be a few days before it is accepted, applied, and
available.
Not sure how to fix the “can’t write to /opt/local/share/doc/sumo” but having
the tutorials at all is a bonus. However any suggestions on this are
appreciated.
Feel free to ask about any other issues you run into.

import traci
I tried commenting out this line:
sys.path.append(os.path.join(os.environ.get("SUMO_HOME", os.path.join(
os.path.dirname(__file__), "..", "..", "..")), "tools")) # tutorial in
docs
and I also tried commenting out the whole block, but it still isn't working for
me. Are these the lines that you were referring?
Thanks!

Hi Tom,
Thanks for your help! Specifically what I'm trying to do is follow the tutorial
given: here http://sumo.dlr.de/wiki/Tutorials/TraCI4Traffic_Lights
I am not sure where to point the environmental variable SUMO_HOME:
rescomp-13-265598:traci_tls Evan$ ls
data embedded.py runner.py
rescomp-13-265598:traci_tls Evan$ pwd
/opt/local/share/doc/sumo/tutorial/traci_tls
rescomp-13-265598:traci_tls Evan$ python runner.py
please declare environment variable ‘SUMO_HOME' as the root directory of your
sumo installation (it should contain folders 'bin', 'tools' and 'docs')
I was unable to locate any sumo directory that contains bin, tools and docs.
I've attached the output of "port contents sumo" to this email under the file
logfile.txt. Any ideas?
Ah, right. There are a few changes needed in the source code to get it to fit
into /opt/local/bin/, /opt/local/lib/ etc to remove the need for SUMO_HOME.
In this case, there is a try/except in the runner.py file which has a
commented-out reference to SUMO_HOME (good) but the line actually extended to
two lines and the second one caused an error (bad). The only case for the
except clause warns you to set SUMO_HOME (which is not actually the root cause
of the problem).
Try modifying runner.py to comment-out the line immediately following the one
with SUMO_HOME and try again. Let me know if you have additional trouble, and
I’ll think about how to fix the problem (though it exceeds my sed expertise at
the moment!).

Thanks!

Hi. I’m the maintainer of the sumo port, and the python scripts and libraries
are definitely installed.
What is the symptom of “lacks python support”? Could it be that you are not
finding a particular script? If so, perhaps it would help to know that all of
the scripts (over 100 of them) are prefixed with a “sumo-“ to avoid name
collisions in /opt/local/bin/. Also, underscores in program names are replaced
by dashes for name consistency.
“port contents sumo” might help you locate what you need, and will give a clue
about where other files such as libraries are placed.
