Unhelpful error when trying to export with broken npm
Looks like my npm is in a weird state.
pi@raspberrypi:~/code/tempplot $ npm
pi@raspberrypi:~/code/tempplot $ echo $?
1
Anyway, this leads to an unhelpful error when I try to export!:

Hi @Grazfather; Thanks for posting this issue, and for doing a bit of hunting into your npm environment.
Do you have a suggestion for how to improve the error message? I do believe that Unable to execute static embed is in a log statement in the code somewhere, so we could easily rewrite that line to say something more informative.
Also, are you running Oz on a raspberry pi!?
Thanks

I had a 'better' error before I tried to install the vega stuff with npm, it told me that I had to install them. I think a similar message that hinted that it's a problem that lives in javascript land would be helpful.

I'm trying to!

Yeah; I think something like Unable to execute static embed - check that vega-cli tooling is properly functioning (vl2png, vl2svg, etc) would be pretty clear and helpful. Thoughts on that?

That's fantastic! I'd love to know more about this! If you can, please share a bit more here.
Thanks!

That would be pretty helpful!
Installed npm (https://nodejs.org/en/download/), then vega (npm install -g vega), and then vega-cli (npm install -g vega-cli) on windows, and made sure that the vg2png etc are on path (C:\Users\boris\AppData\Roaming\npm).
Running an embed still gives "Unable to execute static embed", and also "Cannot run program "which"" (which makes sense, as we are on windows).
