Build fails on Ubuntu with "sw_vers not found"

[cliffgold]

I'm getting the error:
adding /home/travis/build/nvdla/doc/.env to cache
creating directory /home/travis/build/nvdla/doc/.env
sh: 1: sw_vers: not found

on build #16 for pull request #5. I see that appium/appium#1580
had the same error when iOS checks were done on Ubuntu. Could this be the same problem? I'm running Ubuntu.

Or am I doing something wrong?

I admit that I am a Travis-CI novice :-) Does it work for you if you install Sphinx, and then run 'build-html.sh' in this doc tree? The Travis stuff is really only there to automatically push to GitHub Pages on commit.

I get some warnings, but the build does complete.

@cliffgold Seems this issue went stale. Did you resolve it?
