solana/锚定错误：（划定依赖关系）未能获得包装元数据：`货运元数据带有错误：更新Crates.io index
我昨天刚刚设置了一个新的锚点项目，每个命令运行顺利。
今天，我安装了一个新的锚点项目。我运行锚测试查看项目是否正确设置。我遇到了这个错误：
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 = "^0.23.0"`
candidate versions found which didn't match: 0.24.2
location searched: crates.io index
required by package `myAnchorProject v0.1.0 (.../programs/myAnchorProject)`
尚不清楚候选版本的含义。我删除了node_modules，并使用“@project-serum/adnador”安装它：“^0.24.2”，仍然相同的错误。
我清除lib.rs和测试文件以查看不同的内容，但仍然会出现相同的错误。
执行货物更新正在给出相同的错误
I just set up a new anchor project yesterday, every command runs smoothly.
Today I installed a new anchor project. I run anchor test to see if the project is set up correctly. I am getting this error:
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 = "^0.23.0"`
candidate versions found which didn't match: 0.24.2
location searched: crates.io index
required by package `myAnchorProject v0.1.0 (.../programs/myAnchorProject)`
It is not clear what candidate versions mean. I deleted node_modules and install it with "@project-serum/anchor": "^0.24.2", still same error.
I clear the lib.rs and testing file to see something different, but it still gives the same error.
executing cargo update is giving same error

package.json中的依赖性不是问题，这是由于使用了Yanked Rust Crateadnakor-lang所有其他版本
0.24.2 已被拉紧，因此您无法构建任何具有依赖的货物项目。请参阅此处 https://crates.io/crates/crates/anchor-lang/versions 您需要使它工作是
转到
＆lt; your-project-root＆gt;/programs/myanchorproject/cargo.toml。我假设您的程序名称为
myanchorProject或用您的程序名称替换。您当前的CARGO.TOML必须看起来像
您需要将锚式版本升级到
0.24.2或任何其他版本（如果可用）。因此，您的最终货物。汤姆尔应该看起来像
It's not the problem with dependency in your
package.jsonis due to the use of yanked rust crateanchor-langall the other version the
0.24.2have been yanked so you can't build any cargo project which has yanked dependeny.refer here https://crates.io/crates/anchor-lang/versions
what you need to do get it working is
go to
<your-project-root>/programs/myAnchorProject/cargo.toml.I'm assuming your program name is
myAnchorProjector replace it with your program name.your current cargo.toml must look something like
you need to upgrade the anchor-lang version to
0.24.2or any other version if available which is not yanked.so your final cargo.toml should look like
