You need to register the source map support before babel register…

[dangreen]

@wmertens mmmm how ? example ?

[dangreen]

require("source-map-support").install();
require("babel-register")();

require("./test.js");

and all works. I think developers should write some about it in documentation.

Oh wow, I spent all of yesterday trying to work this out! Any chance of adding it to the readme?

[dangreen]

@tamlyn I'm sorry I made a mistake. See working with babel here.

@tamlyn how is it done without sails?

[graingert]

fyi, babel-register includes support for source-map-support directly. https://github.com/babel/babel/blob/dc1f40540de11045bb4714350350e012fee4f93e/packages/babel-register/src/node.js#L11-L24
