demo setup currently not working anymore

[almereyda]

I've tried to follow the instructions, but struk when I was asked

Unable to find a suitable version for polymer, please choose one:
    1) polymer#0.3.3 which resolved to 0.3.3 and is required by code-mirror#f3d6ffbf24, doc-leaves#7a56a3db7c, marked-element#92d7b8445f, pouch-db#c4d4871168, syntax-highlight#ac6a1f321e, vege-table#ffea68deef 
    2) polymer#^0.5.0 which resolved to 0.5.2 and is required by core-component-page#0.5.2, core-component-page#0.5.2, core-meta#0.5.2, core-overlay#0.5.2, core-transition#0.5.2Prefix the choice with ! to persist it to bower.json

If I did rm -rf bower_components/platform && bower install vege-table --save it even installed [email protected], but I don't know which polymer it depends on.

Is there a known way to get it running again?
