Narrative:
On climb out from ZZZ2 passing through 13;000 feet I received a left bleed duct warning message. I directed the pilot monitoring to perform the QRH procedure. The procedure had us to descend to 10;000 feet for unpressurized flight; so we asked ATC for a lower altitude. While descending the flight attendant called and informed us that there was smoke in the cabin. I declared an emergency and asked for the closest airport; and ATC cleared us to ZZZ. When we called the flight attendant to give the time until landing; she told the pilot monitoring that the cabin had cleared. Upon landing we exited the runway; and decided to taxi to gate since it was near the clearing taxi way. All the passengers exited through the passenger door stairs.the l(r) bleed duct message doesn't ever try to isolate between left or right bleed system; and never tries to start the APU. Maybe some pressure for the right pack in this case might not have had smoke in the cabin.
