rustup update报错，如何移除wasm32-wasi并添加wasm32-wasip1？

执行rustup update时遇到以下错误：

error: component 'rust-std' for target 'wasm32-wasi' is unavailable for download for channel 'nightly'
error: Sometimes not all components are available in any    given nightly. If you don't need the component, you could try a minimal installation with:
error:
error:     rustup toolchain add nightly --profile minimal
error:
error: If you require these components, please install and use the latest successful build version,
error: which you can find at <https://rust-lang.github.io/rustup-components-history>.
error:
error: After determining the correct date, install it with a command such as:
error:
error:     rustup toolchain install nightly-2018-12-27
error:
error: Then you can use the toolchain with commands such as:
error:
error:     cargo +nightly-2018-12-27 build

根据官方信息，自2024-10-17起nightly渠道不再提供wasm32-wasi目标，需切换为wasm32-wasip1。以下是移除旧目标并添加新目标的步骤：

步骤1：移除旧的wasm32-wasi目标 #

针对nightly工具链执行移除命令：

rustup target remove wasm32-wasi --toolchain nightly

若该目标属于全局默认工具链，可省略--toolchain nightly参数：

rustup target remove wasm32-wasi

步骤2：添加新的wasm32-wasip1目标 #

针对nightly工具链添加新目标：

rustup target add wasm32-wasip1 --toolchain nightly

全局默认工具链则使用：

rustup target add wasm32-wasip1

验证操作 #

执行以下命令确认目标已切换：

rustup target list --toolchain nightly | grep wasm

输出应显示wasm32-wasip1 (installed)，且wasm32-wasi不再标记为已安装状态。
