I&#x27;m using `gulp servo` which appears to use that switch: <a href="https:&#x2F;&#x2F;github.com&#x2F;browserhtml&#x2F;browserhtml&#x2F;blob&#x2F;master&#x2F;gulpfile.babel.js#L148" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;browserhtml&#x2F;browserhtml&#x2F;blob&#x2F;master&#x2F;gulpf...</a> .  Used the binary in the target&#x2F;release folder... not sure what I could have done wrong.
