[wasm] ThreadPoolBuildError: operation not supported on this platform

[nolanlawson]

Describe the bug

Here is a minimal repro. The repro is using minifySync to minify the latest jquery.js:

const fs = require('fs')
const { minifySync } = require('@swc/wasm')

const src = fs.readFileSync('./jquery.js', 'utf8')

minifySync(src, {})

Input code

(See repro above)

Config

None

Playground link

No response

Expected behavior

No error, the code is minified.

Actual behavior

The code exits with error code 1 and this output:

panicked at 'The global thread pool has not been initialized.: ThreadPoolBuildError { kind: IOError(Error { kind: Unsupported, message: "operation not supported on this platform" }) }', /home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/rayon-core-1.9.2/src/registry.rs:170:10

Additional context

Apparently (image-rs/image#1496 (comment)) the error is caused by the rayon Rust crate.

Also my environment (macOS, Intel, 2020 13-inch MacBook Pro) may be relevant here:
