Anchor dependency issue

Question

got an dependency issue when trying to build anchor

My anchor version:

>>> anchor --version
anchor-cli 0.24.1

I've initialized project:

anchor init solana-escrow-anchor

Then, move into directory to compile this:

>>> anchor build    
BPF SDK: /Users/n.duginets/.local/share/solana/install/releases/stable-616d8d67978c325087cc5a9f33307f54eee48b6e/solana-release/bin/sdk/bpf

And got this strange error.

How can I fix this?

Answer 1

According to the error notice, there is a dependency issue with the version of the "aho-corasick" crate. The version required by the "regex" crate and several of the dependencies of the "solana-escrow-anchor" project are incompatible.

You can try one of the following fixes to resolve this problem:

• List item: The "solana-escrow-anchor" project's Cargo.toml file should be modified to match the version requirement of the "regex" crate for the "aho-corasick" crate. To ensure compatibility with the most recent version of the "regex" crate, you can try altering the "1.0.0" requirement to "0.7.0." Run the "anchor build" command once more after that.

• List item: Update the version of the "regex" crate to one that is compatible with the version of "aho-corasick" required by the other dependencies if altering the version requirement of the "aho-corasick" crate is not possible. Change the "regex" crate's version requirement in the "solana-escrow-anchor" project's Cargo.toml file to do this. Run the "anchor build" command once more after that.

• List item: Utilising a dependency resolver tool, such as "cargo-edit" or "cargo-tree" to examine the dependency tree and identify the problem's underlying causes, is another option. These tools can show you which versions of the dependencies are incompatible and offer a potential fix.
