Cargo build-sbf error

1

Lock file version 4 requires -Znext-lockfile-bump

I changed the version, but the error is still there. I also tried rebuilding the Cargo.lock file, but it didn’t fix the problem.

Your Rust version is too old. You must install the current version. If you have rustup, then run:

rustup update

If that doesn't work because you have Rust packaged from some other source, then uninstall Rust, and install a good version from https://rustup.rs

anarchsun
i was getting this berror when cargo build-sbf or anchor build ..:

cargo build-sbf
error: failed to parse lock file at: /home/anrchsun/devs/ana-cain/Cargo.lock

but if you all could read carefully the solution was given in error message:

Caused by:
lock file version 4 requires -Znext-lockfile-bump

so i ran :slight_smile:

,,, bash
cargo build-sbf -- -Znext-lockfile-bump
''''
and everything worked fine...

Updating your toolchain is the solution as the first reply answers.

But there is also another possible outdated cargo source other than cargo CLI.
If your cargo plugin CLI uses an old cargo lib, the behavior of parsing lockfile is determined by the lib, even though your cargo CLI is the latest.

Wrong Solana version
the error is du to anchor using cargo and rustc from within your Solana release not rustup update toolchains...

One thing that worked was opening corgo.lock file and putting a "3" in version instead of 4.... It will compile but you'll run into a rusc or cargo using 1.79 but you are using 1.75... Rustup update won't fix that as i said it uses rust from within solana...

To fix both errors

just update your bsolana cli --version to a 2.1.x version just go take a look at the different solana-program versions and rust version at crates.io...
you can go chexk out solana-program versions and rust requierments here:
(cant post more links)

solana-program@=>2.1.0

using rust crates, its best to match all basiv solana instances to same version and also to use the same cli version ex: solana-program: 2.1.11 solana-sdk: 2.1.11, solana-???? 2.1.11 all the same.

Then update your solana using:

sh -c "$(curl -sSfL https://release.anza.xyz/stable/install)"

just replace /stable with v^2.1.0 or any version above 2.1.x

Then if you run into dependencies problems use the same crates.io link and search for crate or dependency and look at its dependencies and match..
Generally cargo add fetches the right version if no entry is present...
