zkcrypto / zkp Goto Github PK

I'm getting the following errors when trying to compile code sig_and_vrf_example.rs.
Rust version: 1.47.0

ERROR 1
error[E0308]: mismatched types

= note: expected reference &zkp::curve25519_dalek_ng::scalar::Scalar
found reference &curve25519_dalek::scalar::Scalar

zkp = "0.8.0"
rand = "0.7"
curve25519-dalek = { version = "2", default-features = false, features = ["serde", "std"] }

ERROR 2
Also, if trying using the latest version of rand and curve25519, get a different error:
