I am using MacOSX 13 High Sierra.
I updated Node.js and installed atom2yasnippets.
I can print the help but that is it.

I have tried the following commands

atom2yas -u "file:///Users/blaine/software/yasnippets/subi.cson" -o ./dist

atom2yas -u file:///Users/blaine/software/yasnippets/subi.cson-o file///Users/blaine/software/yasnippets/dist/

atom2yas -u /Users/blaine/software/yasnippets/subi.cson -o /Users/blaine/software/yasnippets/dist

atom2yas -u rawCSONAtomSnippetURL -o ./dist

All of the above give the error message:

(node:40501) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: only absolute urls are supported

Here is the content of the cson file:

'.text.tex, latex.ing, comment.line.percentage.tex, meta.no-spellcheck':
'subsection with label and index':
prefix: 'subi'
body: '''
