Unable to locate the @bytecodealliance/preview2-shim package

[peter-jerry-ye]

Hi,

I have both @bytecodealliance/preview2-shim and @bytecodealliance/jco installed with npm install.

{
	"dependencies": {
		"@bytecodealliance/jco": "^1.4.0",
		"@bytecodealliance/preview2-shim": "^0.16.4"
	}
}

When I run npx jco serve xxx.wasm, I got the following error:

(jco serve) Error: Unable to locate the @bytecodealliance/preview2-shim package, make sure it is installed.

It seems that the import.meta.url here:

jco/src/cmd/run.js

Line 88 in 3946278

let preview2ShimPath = fileURLToPath(new URL('../../node_modules/@bytecodealliance/preview2-shim', import.meta.url));

gives me the path to the node_modules/@bytecodealliance/jco/src/cmd/run.js

Versions:

• Node.js v22.5.1
• npm / npx v10.8.2

Seeing similar behavior node 20, same packages, Windows (in-case it's OS-specific).
