Trying to compile smart contract and it gives me this error, in charge .toml I put the direct routes and nothing. Other smart contracts compile with ink! properly.

Command I use: cargo +nightly contract build --release and error I got:

ERROR: Loading Cargo.toml

Caused by:
     No such file or directory (os error 2)

  • @polkadot/util has multiple versions, ensure that there is only one installed. Either remove and explicitly install matching versions or dedupe using your package manager. The following conflicting packages were found: cjs 10.2.1 node_modules/@astar-network/swanky-cli/node_modules/@polkadot/util-crypto/node_modules/@polkadot/util/cjs cjs 10.1.13 node_modules/@astar-network/swanky-cli/node_modules/@polkadot/util/cjs Dec 23, 2022 at 13:22

Could you add more details to your question, for now is not specified enough to give some valuable input. I can share my experience with swanky-node (maybe is related). When you will try to build firstly the node like below:

tomek@rhei-box:~/workspaces/swanky-node$ cargo build [2022-12-20T22:49:25Z INFO cargo_release::release] Publishing pallet-chain-extension-rmrk Updating crates.io index error: all dependencies must have a version specified when publishing. dependency frame-support does not specify a version Note: The published dependency will use the version from crates.io, the git specification will be removed from the dependency declaration.

You can get errors, but when you execute cargo build --release immediately after cloning repository, everything should compile successfully.
