Answer 1

May be you have not setup the env for FACEBOOK_KEY and FACEBOOK_SECRET

In terminal (if you are using linux or mac)

$ export FACEBOOK_KEY=zzyzyzyzyzyzzy
$ export FACEBOOK_SECRET=zzyzyzyzyzyzzysbdbdsndnds

#now start rails from same terminal
$ rails s

this will now pass the values of FACEBOOK_KEY and FACEBOOK_SECRET to application.

Or second option

provider :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET']

to this

provider :facebook, 'FACEBOOK_KEY', 'FACEBOOK_SECRET'

Diff between using two approaches.

The drawback of second type is, you need to keep the keys into the code repository. which is not a safe approach.
