vg2pdf and vg2png fail with TypeError: Cannot read property 'getContext' of null #2

Open eharkins opened 4 years ago

eharkins commented 4 years ago

Issue: vg2png and vg2pdf both fail;

running 

curl -L https://raw.githubusercontent.com/vega/vega/master/docs/examples/bar-chart.vg.json > test.json
vg2pdf test.json > test.pdf

(also with vg2png) gives:

TypeError: Cannot read property 'getContext' of null

See https://github.com/altair-viz/altair_saver/issues/13 for previous efforts to troubleshoot this. Wondering if it has anything to do with the difference between my env and that in which the vega-cli-feedstock CI tests happen.

Thanks!
