rollup make this issue when I rollup my app

[bernardschyns]

When I run my angular-cli app with jit, I get no problem.. When I try to roll-up following the "tour of heroes" documentation of angular....I catch this message error about "angular2-image-gallery"...

src/main-aot.js → aot/dist/build.js... 'angular2-image-gallery' is imported by src/app/app.module.js, but could not be resolved – treating it as an external dependency
