Solana 锚点构建需要货物版本 2021

Question

我正在尝试运行锚定构建并收到以下响应：

BPF SDK: /root/.local/share/solana/install/releases/1.8.0/solana-release/bin/sdk/bpf
Running: rustup toolchain list -v
Running: cargo +bpf build --target bpfel-unknown-unknown --release
error: failed to download `solana-frozen-abi v1.9.4`

Caused by:
  unable to get packages from source

Caused by:
  failed to parse manifest at `/root/.cargo/registry/src/github.com-1ecc6299db9ec823/solana-frozen-abi-1.9.4/Cargo.toml`

Caused by:
  feature `edition2021` is required

  consider adding `cargo-features = ["edition2021"]` to the manifest

PS：我已经尝试过以下建议：

Answer 1

您的 solana 安装似乎已经过时了。我会安装 1.8.11 或运行 solana-install update

Answer 2

有时，也考虑下载点赞，在我的情况下，我不得不将 Cargo.toml 文件中的 2021 年更改为 2018 年，这很有效
