Looks like this was added for 17.4. I tried it on 17.3 just to be sure, and
got the same failure you did. But for 17.4:

$ erl
Erlang/OTP 17 [erts-6.3] [source] [64-bit] [smp:8:8] [ds:8:8:10]
[async-threads:10] [kernel-poll:false]

Eshell V6.3  (abort with ^G)
1> erlang:system_info(nif_version).
"2.7"
