[ros-users] [Discourse.ros.org] [General] Should we warn (new) users about difficulties with Python 3 and alternative Python interpreters?

[gavanderhoorn]

I agree with you there are quite some conceptual differences, and the workflows of Python and other languages cannot be considered equal, but it's not about having to run `make`, or having to use a build process.

After following the ROS (Ubuntu/Debian) installation tutorial, opening a text editor and writing your first `rospy`-based script, someone with an Anaconda or a (system managed/provided) Python 3 installation will always run into an `ImportError: No module named rospy` error.

That seems to already confuse new users enough that I was wondering whether we should document it.
