Cargo build errors

[GerhardLiebenberg]

Good day. I am trying to build the simple-arbitrage-rs app.
Cargo build gives me the following errors:

Attempt-1
Cargo.toml:
ethers = { git = "https://github.com/thasarito/ethers-rs", feature="abigen" }
Error:
Updating git repository https://github.com/thasarito/ethers-rs
Updating crates.io index
Updating git repository https://github.com/rust-ethereum/ethabi
Updating git repository https://github.com/hyperledger-labs/solang
error: failed to select a version for generic-array.
... required by package elliptic-curve v0.11.6
... which satisfies dependency elliptic-curve = "^0.11.6" (locked to 0.11.6) of package ecdsa v0.13.4
... which satisfies dependency ecdsa = "^0.13.4" of package ethers-core v0.6.0 (https://github.com/thasarito/ethers-rs#a77bf845)

Attempt-2
Cargo.toml:
ethers = { version = "0.6.2", features = ["abigen"] }
Error:
error[E0432]: unresolved import ethers::contract::MultiAbigen
--> build.rs:2:24
|
2 | use ethers::contract::{MultiAbigen};
| ^^^^^^^^^^^ no MultiAbigen in contract

Do I need to install any other software before attempting the build?

Maybe try replacing ethers = { git = "https://github.com/thasarito/ethers-rs", feature="abigen" } with the official repo.

https://github.com/gakonst/ethers-rs

I tried that as well. Same error.

It looks like MultiAbigen is a new feature. Perhaps that is why it is not in the crate's version = "0.6.2" yet.
Do you think the crate has a nightly version I could try?

[thasarito]

Have you tried cargo clean and build again.

[thasarito]

Also, may I ask what your purpose of running?

FYI that this is incomplete and the arbitrage logic may not be correct.

[GerhardLiebenberg]

I ran cargo clean, but same errors.

I want to run the code to learn how to interact with the flashbots contracts.
I did not get it working using the ethers-rs examples.
Don’t worry about incompleteness :-)

[thasarito]

Can you get it to work now?

[GerhardLiebenberg]

I got the parts that I need working - by duplicating them in a new application.
I have not yet found the parts that gave me problems in the first place.
I will let you know if I find anything not working.
Thanx for your help.
