Unable to run drake-visualizer after successful build

[edrumwri]

I built with the default cmake options.

I pointed my PYTHONPATH to $DIRECTOR_HOME/src/python (not sure if this is the recommended workflow)

Running drake-visualizer gave me the following error message:

./build/install/bin/drake-visualizer

Hi @edrumwri you shouldn't set PYTHONPATH. Director is composed of .py and .so files and they are all copied into the install tree under build/install/lib/python3.6 (or whatever version of python was used to compile. The drake-visualizer program will automatically search this path. If you set PYTHONPATH then it finds director from the source tree which has the .py files but not the .so files.

[edrumwri]

Hmm.. If I don't do that, then it has a different complaint:
ModuleNotFoundError: No module named 'director'

After building, should I be doing a make install somewhere?

This is all on a fairly fresh ubuntu 18 install, btw.

[patmarion]

Director is tested in ubuntu 18, it should work. It uses a "superbuild" which builds and installs all dependencies. Running from the build/install dir should be all that is required, no extra steps. Is there any more output, maybe printed before the ModuleNotFoundError? If you look under build/install/lib/python3.6/site-packages do you see the director python files?

[edrumwri]

No, that is the only output.

The files in build/install/lib/python3.6/site-packages (there is also a build/install/lib/python3.7/site-packages, which seems to have an identical list of files) follows:
