Rust E0463 构建 Dioxus Fullstack，但安装了 wasm32-unknown-unknown 目标

Question

运行

dx build --features web --release

或

cargo build --target wasm32-unknown-unknown

返回以下错误：

[INFO] 🚅 Running build command...
error: Broken pipe (os error 32)
Error: 🚫 Building project failed: error[E0463]: can't find crate for `std`
  |
  = note: the `wasm32-unknown-unknown` target may not be installed
  = help: consider downloading the target with `rustup target add wasm32-unknown-unknown`

但是，当我运行

rustup target add wasm32-unknown-unknown

时，它会打印

info: component 'rust-std' for target 'wasm32-unknown-unknown' is up to date

当我运行

rustup show

时，目标似乎已安装：

Default host: aarch64-apple-darwin
rustup home:  /Users/myhomedir/.rustup

installed targets for active toolchain
--------------------------------------

aarch64-apple-darwin
wasm32-unknown-unknown

active toolchain
----------------

stable-aarch64-apple-darwin (default)
rustc 1.76.0 (07dca489a 2024-02-04)

我不明白为什么没有为此目标编译标准库。

Answer 1

事实证明 Rust 是通过

homebrew

和

rustup

安装的。删除自制软件安装解决了这个问题。感谢这个答案：https://stackoverflow.com/a/74549777/22985331
