Getting Started js-libp2p: ERR_PACKAGE_PATH_NOT_EXPORTED

[jehaverlack]

I'm attempting to follow the direction at:

• https://docs.libp2p.io/guides/getting-started/javascript/

$ cat /etc/debian_version 
12.4

$ node --version
v20.11.0

But I keep getting this error:

$ node src/index.js 
node:internal/modules/esm/resolve:303
  return new ERR_PACKAGE_PATH_NOT_EXPORTED(
         ^

Node.js v20.11.0

Here is my src/index.js and package.json

src/index.js

      protocolPrefix: 'ipfs', // default

await node.start()
console.log('libp2p has started')

// print out listening addresses
console.log('listening on addresses:')
node.getMultiaddrs().forEach((addr) => {
  console.log(addr.toString())

// ping peer if received multiaddr
if (process.argv.length >= 3) {
  const ma = multiaddr(process.argv[2])
  console.log(`pinging remote peer at ${process.argv[2]}`)
  const latency = await node.services.ping.ping(ma)
  console.log(`pinged ${process.argv[2]} in ${latency}ms`)
} else {
  console.log('no remote peer address given, skipping ping')
}

const stop = async () => {

  await node.stop()
  console.log('libp2p has stopped')
  process.exit(0)

process.on('SIGTERM', stop)
