Firebase ionic2-rc0 and rollup - "rollup: Use of `eval` is strongly discouraged"

[21:44:09] rollup: Use ofeval(in c:\XXX\node_modules\angularfire2\node_modules\firebase\firebase.js) is strongly discouraged, as it poses security risks and may cause issues with minification. See for more details

Anyone has seen this error with rollup?

I have configured Firebase according to this blog post:

Got the answer on stackoverflow but I’ve not tried the solution.
