python2 to python3 switch in ros serial #560

Open nixinator opened 3 years ago

I'm having problems with melodic , it's seems to run things here using python2, i could not get roslaunch/rosrun to execute these scripts using python3. This might be environmental problems on the jetson. However python3/python2 are available on the system.

git checkout 8.0 , solves the problem , as these scripts are still python2 compatible. :-)

Would it be possible to have better descriptions in change log of 8.0 to say that was the last release that supported python2?

http://wiki.ros.org/UsingPython3. has more gory details, however this stuff is hard!!! Happy roboteering!

It's quite possible the i'm just another victim of

I think most of the scripts use /usr/bin/env python (or /.../bin/python). So you can use python3 by making /usr/bin/python a link to python3 rather than python2.

I'll give that a try... thanks for tips.

symbolic links, i used them 30 years ago, i'm not sure if i'm happy or sad that they are still in use today.
