Steps to reproduce the error:

code:

/src/app.js

const  IPFS = require('ipfs')

const Repo = require('ipfs-repo')

const  repo_path = "/Users/xiaoyu/.jsipfs"
const repo = new Repo(repo_path)


repo.init({ cool: 'config' }, (err) => {
    if (err) {
        throw err
    }

    repo.open((err) => {
        if (err) {
            throw err
        }

        console.log('repo is ready')
    })
})

const ipfs = new IPFS(
    {
        repo:repo_path,


        start: true,
        EXPERIMENTAL:{
            pubsub:true
        }

    }
)

I believe there is some confusion on this test, let me try to break it down from what I can understand reading the info you shared. Btw, thank you for sharing all the steps!

a) You don't need to bring the repo module up

All you need is just to do:

const  IPFS = require('ipfs')
const  repo_path = "/Users/xiaoyu/.jsipfs"

const ipfs = new IPFS({
  repo: repo_path,
  EXPERIMENTAL: {
    pubsub: true
  }
})

b) If you are looking to run this application on the browser, the path has no meaning with regards to your fs

This might be confusing but essentially a Browser has no access to the local file system, it uses its own sandboxed datastore (LocalStorage or IndexedDB).

This means that you can even simplify more your app.js to just:

const  IPFS = require('ipfs')

const ipfs = new IPFS({
  EXPERIMENTAL: {
    pubsub: true
  }
})

Try it again with this latest node set up and let me know how it went :)

thank you for your help. I tried both the a and b methods. The browser's console produces the same error.
