this repository just for reproduce the error that module imports a non-existent function message when uploading wasm file to node.
using ink version: tag = "v2.0.0", cargo--contract version is 0.5.0 and node of substrate version is: version 2.0.0-alpha.4-0b3020796-x86_64-linux-gnu
Proceed as follows:
1、 add schnorrkel dependency in cargo.toml,for example:schnorrkel = { version = "0.9.1",features = ["u64_backend"], default-features = false};
2、using cargo contract build command generate wasm file and cargo contract generate-matedata generate metadata.json
3、start substrate node: RUST_LOG="runtime=debug,substrate=error" ./substrate --dev
4、open app in browser,connect local node;
5、uploading wasm file,terminal will appearance information:
