Reproduce Steps
pnpm installpnpm build
You will see the incorrect output like this:
function foo(bar) {
return bar;
}
const version = 'fooooooooo';
async function main() {
const { fooVersion } = await import("./900.js").then((mod)=>({
fooVersion: mod.version
}));
foo(fooVersion);
}
export { main, version };where 900.js does not have any export
