Research direction

Start with the reproduction at https://github.com/davidlanger/factor-bundle-moment-timezone and install moment-timezone before moment, then compare the resulting bundle with the reverse installation order. Trace whether the duplicate moment dependency breaks factor-bundle or the package layout, and consider the issue done when the reproduction produces a working bundle consistently.

Written by the indexing model from the issue text.

Description

factor-bundle creates broken bundles when required modules have linked dependencies. This happens for example when installing moment-timezone and afterwards moment. So moment exists two times in the node_modules folder, once for moment-timezone and once in moment. This seems to break browserify. When installing the modules the other way around the bundle does not break (this time there is only one moment).

I don't know if this is more of a problem with the way npm install modules when they have duplicate dependencies or if this is a problem with factor bundle.

I set up a test case over at: https://github.com/davidlanger/factor-bundle-moment-timezone
