When I was in step 9 of the tutorial named "Solana 101", I was trying to build my first smart contract. But when I use the command as the book says, I got an unexpected error:
$ yarn run solana:build:program
yarn run v1.22.17
$ cargo build-bpf --manifest-path=contracts/solana/program/Cargo.toml --bpf-out-dir=dist/solana/program

We all know this is not about yarn itself, so I google and google and google...
Most of the solutions are similar, the first solution is cargo build-bpf fails, after I tried the answer which has the most thumbs-ups, I got another error which means not work:
$ yarn run solana:build:program
yarn run v1.22.17
$ cargo build-bpf --manifest-path=contracts/solana/program/Cargo.toml --bpf-out-dir=dist/solana/program
BPF SDK path does not exist: /Users/alice/.local/share/solana/install/active_release/bin/sdk/bpf: No such file or directory (os error 2)
error Command failed with exit code 1.

After careful comparison, I found my situation may differ from the above question. So I keep searching and I found another question on StackOverflow with the same keyword "BPF SDK path does not exist". In the solution, it told me to up the version of Rust to date and check the version of Solana CLI, so I tried the following:
I updated the Rust and reinstall the Solana CLI with an exact version, and after that, I tried the build command again:
$ yarn run solana:build:program
yarn run v1.22.17
$ cargo build-bpf --manifest-path=contracts/solana/program/Cargo.toml --bpf-out-dir=dist/solana/program

To deploy this program:
$ solana program deploy /Users/alice/Codes/Private/learn-web3-dapp/dist/solana/program/helloworld.so
The program address will default to this keypair (override with --program-id):
/Users/alice/Codes/Private/learn-web3-dapp/dist/solana/program/helloworld-keypair.json
✨ Done in 23.40s.
Wow! It works! I think maybe the previous version of Solana CLI I installed is somehow broken or not suitable for the Rust version. I'm relieved to finally be able to compile the program.
