Changing the Output Folder in canvas-sketch doesn’t work

I’ve just tried to set up canvas-sketch. I need to see my output files and this instruction didn’t work. Any opinion?
My steps of installing and changing the default output folder:
npm install canvas-sketch-cli -g ; mkdir my-sketches ;cd my-sketches; canvas-sketch sketch-01.js --new --open
and then for changing default folder(actually I didn’t even find the default folder):canvas-sketch sketch-01.js --output=output/01
There is no error btw.
