cargo build-bpf no such command: `+solana` running build:program-rust

Question

Ran the code npm run build:program-rust getting this error I've tried uninstalling and reinstalling rustup and also solana tool chain still nothing

[email protected] build:program-rust cargo build-bpf --manifest-path=./src/program-rust/Cargo.toml --bpf-out-dir=dist/program

info: uninstalling toolchain 'solana' info: toolchain 'solana' uninstalled error: no such command: +solana

    Cargo does not handle `+toolchain` directives.
    Did you mean to invoke `cargo` through `rustup` instead?

Answer 1

This could come from a couple of sources:

• Rust is old: be sure to upgrade with rustup update stable
• the Solana toolsuite isn't installed: be sure to install it https://docs.solana.com/cli/install-solana-cli-tools
• the Solana toolsuite is old: be sure to upgrade with solana-install init 1.17.13 (as of this writing)

Answer 2

This error has to do with a deprecated version where as before it would use cargo build - bpf but got deprecated wich probably means ur anchor cli its also deprecated.

Btw why are you calling this :npm run build:program-rust ??

if you are building in native rust its cargo build if you are using anchor should be anchor build
