error: lock file

[phamminh0811]

Hi! I'm stuck trying to optimize a smart contract.
When I run rust-optimizer in the root folder of a clean copy of https://github.com/InterWasm/cw-template I get this problem:
docker run --rm -v "$(pwd)":/code --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry cosmwasm/rust-optimizer:0.12.10

error: the lock file /code/Cargo.lock needs to be updated but --locked was passed to prevent this
If you want to try to generate the lock file without accessing the network, remove the --locked flag and use --offline instead.

Can somebody help me please?

I think the problem is that optimize.sh file has the RUSTFLAGS='-C link-arg=-s' cargo build --release --lib --target wasm32-unknown-unknown --locked command, but I don't know how to fix it

cw-template cannot be used directly. You need to generate a project from the template first using cargo-generate. Did you do that?

Yes, I do use cargo-generate, but not work.

[webmaster128]

okay. Then you probably need to run cargo build to update the Cargo.lock before running rust-optimizer.

Not work, either. It's still the same error

[KirilMihaylov]

You have to run cargo update. This will update all crates assuming SemVer compatibility /a.k.a. will update only minor and patch versions/ on behalf of the crates.

Awesome, problem is fixed. Thanks so much
