createCanvas is not a function

I’m trying to use prismarine-viewer.headless, specifically with this line: viewer(mc, { output: 'pov.png', frames: 1, width: 1920, height: 1080 }); However, upon executing that line, this error pops out:

/project/node_modules/prismarine-viewer/lib/headless.js:18
  const canvas = createCanvas(width, height)
                 ^

TypeError: createCanvas is not a function

To add: prismarine-viewer is on 1.17.0, and mineflayer is on 3.2.0. Edit: Updated prismarine-viewer to 1.18.0 and mineflayer to 3.3.1; no difference.

Just tried the example/headless.js script with latest version, no issues. Can you please make sure that node-canvas-webgl is actually installed. You can also try to run the example to check if the issue is coming from your script.

Ah right- looks like a lot more than the original line I had used; nevertheless, will give it a shot. Cheers!
