"Could not find vizInterface when import attempted." Error with default settings on Linux.

[patrickwalton]

Steps Followed

• I removed previous basilisk and $HOME/.conan folders.
• Re-clone basilisk: git clone [email protected]:AVSLab/basilisk.git.
• Checkout the 2.3.0 release tag: git checkout v2.3.0.
• Followed the Linux package management steps listed in the install on Linux instructions.
• Created a virtual environment, entered it: python3 -m venv .venv and source .venv/bin/activate.
• Installed wheel, conan<2.0.0, and cmake: pip3 install wheel 'conan<2.0.0' cmake.
• Installed setuptools, because pkg_resources was not found: pip3 install setuptools.
• Built basilisk: python3 conanfile.py.
• Turn on simulation saving and streaming by uncommenting the corresponding lines in examples/scenarioBasicOrbit.py.
• Run a scenario: python3 examples/scenarioBasicOrbit.py

Problem

The build appears successful, but when I run python3 examples/scenarioBasicOrbit.py, I get the following warning:

Could not find vizInterface when import attempted. Be sure to build BSK with vizInterface support.

And with that no Vizard simulation is streamed or file created.

Am I supposed to do something else to build with vizInterface support?

Build Outputs

The documentation said building with vizInterface support is the default and I see that in the beginning of the build output:

python -m conans.conan install . --build=missing -s build_type=Release -if dist3/conan -o opNav=False -o vizInterface=True -o buildProject=True

And vizInterface build appears to have been successful in the build output:
