Hi Yu,

the problem is the sudo. Sudo starts a new shell with only a few environment variables.
I recommend to copy the manhattan example to a local directory which you own (e.g. ~/manhattan) and run all steps in this directory.
Alternatively you can use sudo -E, but I try always to use sudo as less as possible.

Regards, Harald

Thank you Harald and Azise.

I installed SUMO by adding the repository.

I have checked SUMO_HOME with "ls $SUMO_HOME" and "echo $SUMO_HOME". And They work well.

However It still warns me that SUMO_HOME is not set when I use jtrrouter tool.(sudo improves the permisson to output the route file. )

Hi Yu,

How did you install SUMO on Ubuntu (by adding SUMO repository or by building SUMO sources)?

Type echo $SUMO_HOME to check that SUMO_HOME was successfully set.

Azise

Recently I tried to run SUMO on Ubuntu System, and I failed to set the 'SUMO_HOME' environment variable.The figure below shows this error.

According to the link attched, I have tried two methods to solve it. However the problem still exists .https://sumo.dlr.de/wiki/Basics/Basic_Computer_Skills#Linux

1.Temporary solution
The red line shows the failed result.
2.Permannent solution
The part of circle in the figure above is what I add to the .bashrc file. And The /usr/share/sumo directory does contain the folders bin and tools.

So can anyone tell me what mistakes I have made?

Thanks
Yu Xingguang
