Elliptic error on build

[eshcharc]

I get this error when running jspm.bundleSFX:

Error loading "npm:elliptic@6.0.2/package.json!github:systemjs/plugin-json@0.1.0" from "github:mobilexag/plugin-sass@0.0.10/sass-builder"

which fails the build.

Does anyone know what the cause of this error is, and how to solve it?

I want to mention that on Dev mode, everything works perfect.

If I downgrade elliptic to 6.0.0, the previous error is resolved, but I get this new importing error:

TypeError: Cannot read property 'call' of undefined
    at eval (file:../jspm_packages/github/mobilexag/plugin-sass@0.0.10/index.js!eval:25:38)

Could you try to run

$ gulp test:bundleStatic

as mentioned in the README? I tried a $ gulp test:bundleStatic and a $ jspm bundle-sfx test/bundleme.js foo.js as well and everything works fine.

Probably a matter of versions. Solved after upgrading several libs (can't tell which, though).
