Build Error

[stonier]

In a workspace with other packages, a regular colcon build will result in an error:

Running Sphinx v1.6.7                                                                                          

Configuration error:
There is a programable error in your configuration file:

Hmm, it's looking for python2.7. Probably an issue there.

--> Error caused if a user has python-sphinx installed alongside python3-sphinx

I think that adding

#!/usr/bin/env python3

in the conf.py file should solve the issue. I will submit a PR

[stonier]

NB: catkin_pkg is a ROS1 tool. Is there an equivalent for package.xml parsing in ROS2 or is this just a curious anomoly?

Good idea.

Just tried it, but doesn't do the trick :(

/usr/bin/sphinx-build seems to be a generated file on installation. When python-sphinx is installed it has the #!/usr/bin/python bang, when that package is removed (and subsequently only python3-sphinx is installed), then it replaces the bang with #!/usr/bin/python3.

Might want to execute python3 -msphinx which I believe is fundamentally equivalent to sphinx-build with python3.

You can see here that we discussed that. We could not find the colcon equivalency to do so.
