Running dx build --features web --release or cargo build --target wasm32-unknown-unknown returns the following error:
[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`
However, when I run rustup target add wasm32-unknown-unknown, it prints
info: component 'rust-std' for target 'wasm32-unknown-unknown' is up to date
The target appears to be installed when I run rustup show:
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)
I don’t understand why the std lib isn’t compiled for this target.
Turns out Rust was installed via both homebrew and rustup. Removing the homebrew installation fixed this. Credit to this answer: https://stackoverflow.com/a/74549777/22985331
