error on install from npm

getting

warn Error on processPackageConfig
     Package.json dependency ansi-styles set to npm:ansi-styles@^2.2.1, which is not a valid dependency format for npm.
     It's advisable to publish jspm-style packages to GitHub or another registry so conventions are clear.
     To skip npm compatibility install with jspm install npm:aurelia-mask@1.4.0-o "{jspmPackage: true}".

looks like the solution is in https://github.com/jspm/jspm-cli/blob/master/docs/publishing-packages.md#publishing-jspm-style-packages-to-npm

set jspmNodeConversion to false in package.json. that'll make publish slightly more obnoxious.
