`

the Cargo.toml is as follow； I modity the ink = { path = "/Volumes/E/project/github.com/paritytech/ink/crates/ink", default-features = false }; ` [package] name = "trait-incrementer" version = "4.0.0" authors = ["Parity Technologies [email protected]"] edition = "2021" publish = false

[dependencies] ink = { path = "/Volumes/E/project/github.com/paritytech/ink/crates/ink", default-features = false } #ink = { path = "../../../../crates/ink", default-features = false } ` So how can i build this contract。 @cmichi thanks

i modify the ink = { path = "../../../../crates/ink", default-features = false } to ink = { version = "4.2", default-features = false } that it can work
