Rails Assets - 404 with .map extension -


i getting following error several of assets in rails app.

actioncontroller::routingerror (no route matches [get] "/assets/jquery-1.10.2.min.map") 

can shed light on ".map" coming , why? in advance.

it's related new source map support started shipping in jquery 1.9rc1.

you can either follow directions 1.9rc1 link , add compressed, uncompressed, , map files vendor/assets directory or remove source map line uncompressed file (it looks //@ sourcemappingurl=jquery-1.10.2.min.map).

hope helps.
