Cannot build Solana NFT program using `anchor build` command due to rustc version issue

I am writing an NFT program in Anchor framework in Solana blockchain. However, when I tried to build the program using the anchor build command, it always results with an error. The error is:

error: package `solana-program v1.18.11` cannot be built because it requires rustc 1.75.0 or newer, while the currently active rustc version is 1.72.0-dev
Either upgrade to rustc 1.75.0 or newer, or use
cargo update -p [email protected] --precise ver
where `ver` is the latest version of `solana-program` supporting rustc 1.72.0-dev
joshi@Joshis-MBP future-play-nft-anchor-solana % rustup update stable

The current rustc version that I am using is

rustc --version 
rustc 1.77.0 (aedd173a2 2024-03-17)

And, the rustup version that comes after executing the rustup -V command is:

rustup 1.27.0 (bbb9276d2 2024-03-08)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.77.0 (aedd173a2 2024-03-17)`

I have already executed rustup update command to ensure that I using the latest version.

Also, this is a sneak peek to my directory structure:

As you can see, there is no rust-toolchain.toml file in my directory.

Can someone please help me overcome this error? Let me know if you need any more information on the context, I will be happy to provide more.

Solution

  • First use this command to get you solana version: solana --version

    Then use this command : cargo update -p [email protected] --precise 1.17.25 (use your solana --version output value)

    In case it won't work then install solana stable version and command for the same is : sh -c "$(curl -sSfL https://release.solana.com/stable/install)"

    and then proceed with the same steps as above one.
