锚构建错误版本的锚-spl和锚-lang

Question

我正在使用以下锈病存储库：

https://github.com/SmartCodeBlockchainDev/Nelson-NFT-stacking

当我尝试做一个锚构建时，我会得到以下错误：

Failed to obtain package metadata: `cargo metadata` exited with an error:     Updating crates.io index
error: failed to select a version for the requirement `anchor-lang = "^0.20.1"`
candidate versions found which didn't match: 0.24.2
location searched: crates.io index
required by package `nft-staking v0.1.0 (/staking/programs/staking)`

当我将cargo.toml文件更新到这些版本(锚-朗和锚-SPL0.24.2)时，会给出lib.rs中的几个错误：

Some errors have detailed explanations: E0277, E0432, E0599.

Answer 1

这是因为所有旧版本的锚都是按下的：https://crates.io/crates/anchor-lang/versions

您可以通过Cargo.toml中的git标记强制执行所需的版本：

anchor-lang = { git = "https://github.com/project-serum/anchor", tag = "v0.20.1" }

但是，如果较早版本的锚有漏洞，则可能存在安全问题。

Answer 2

您必须将锚版本降级为0.21.0。

如果您在windows机器上，您可以简单地使用npm i -g @project-serum/anchor-cli@^0.21.0

但是，如果您使用的是WSL或Ubuntu，则必须运行sudo apt-get update && sudo apt-get upgrade && sudo apt-get install -y pkg-config build-essential libudev-dev

然后使用cargo install --git https://github.com/project-serum/anchor --tag v0.21.0 anchor-cli --locked从源代码构建特定版本。

请记住，必须安装cargo才能运行此命令。

如果问题仍然存在，您的~/.cargo/registry/index目录将被破坏。删除它，然后再次运行cargo update。“

要在WSL中打开它，只需在ubuntu终端中键入explorer.exe .即可。

别忘了.

Answer 3

cargo install --git https://github.com/project-serum/anchor --tag v0.24.2 anchor-cli --locked

然后，在projects文件夹的cargo.toml中，使锚-lang=0.24.2而不是0.20.1。

我也有同样的问题，这件事对我来说很有效
