When I execute the command cargo build-bpf, I encounter an error. How can I resolve this issue? error: package `libp2p-allow-block-list v0.3.0 (https://github.com/sigp/rust-libp2p/?rev=cfa3275ca17e502799ed56e555b6c0611752e369#cfa3275c)` cannot be built because it requires rustc 1.73.0 or newer, while the currently active rustc version is 1.72.0-dev Either upgrade to rustc 1.73.0 or newer, or use cargo update -p libp2p-allow-block-list@0.3.0 --precise ver where `ver` is the latest version of `libp2p-allow-block-list` supporting rustc 1.72.0-dev solana-cli:1.18.4 rustc: 1.76.0 rustup: 1.26.0

Similar to https://solana.stackexchange.com/a/9799/84 : if you need to use a newer version of the Solana Rust compiler, you can use the --tools-version argument. In your case, you can try: cargo build-sbf --tools-version v1.41

This solution Solves Everything!: Type these in the terminal: solana-install init 1.18.18(or latest version/version/version you’re using, mine worked with 1.18.18) cargo add solana-program@=1.18.18 cargo update -p solana-program@1.18.18 Cargo clean Anchor clean Anchor build This works because using the Solana init command above FIRST makes sure that the build tools are properly initialized.
