SPL-Token crate throws: failed to select a version for the requirement `toml_edit = "^0.18"`

Question

I have been following a tutorial on Solana native development and need to interact with SPL-Token crate at some point.

However, I can not build (cargo-build-bpf), it throws:

BPF SDK: /Users/user1/.local/share/solana/install/releases/1.9.28/solana-release/bin/sdk/bpf
cargo-build-bpf child: rustup toolchain list -v
cargo-build-bpf child: cargo +bpf build --target bpfel-unknown-unknown --release
    Updating crates.io index
error: failed to select a version for the requirement 'toml_edit = "^0.18"'
candidate versions found which didn't match: 0.14.4, 0.14.3, 0.14.2, ...
location searched: crates.io index
required by package 'proc-macro-crate v1.3.0'
    ... which satisfies dependency 'proc-macro-crate = "^1"' (locked to 1.3.0) of package 'num_enum_derive v0.5.7'
    ... which satisfies dependency 'num_enum_derive = "^0.5.7"' (locked to 0.5.7) of package 'num_enum v0.5.7'
    ... which satisfies dependency 'num_enum = "^0.5.4"' (locked to 0.5.7) of package 'spl-token v3.5.0'
    ... which satisfies dependency 'spl-token = "^3.5.0"' (locked to 3.5.0) of package 'core-4 v0.1.0 (/Users/rog/Desktop/Solana Development/Buildspace/core-4)'

I tried to build on Windows10 (WSL) and on Mac, the result is exactly same.

Any ideas?

Answer 1

The issue is caused by an outdated Solana version. Updating Solana through CLI helped.

Answer 2

Upgrading Solana CLI tools to 1.14.13, and using anchor 0.25.0 fixed this for me also. (previously using Solana CLI version 1.9.29 and anchor 0.24.2 for compatibility with solana fork running an older version)

Answer 3

Updating rust and cargo fixed it for me

1. rustup update
2. cargo install cargo-update
3. cargo install-update -a
