• Subsystem:

Severity:

Critical

Description:

I've been working on a project for months. Updated IPFS to the latest version, and now when I try to require it, I get this error.

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in C:\Users\marye\onedrive\desktop\athenae 
server\node_modules\ipfs\package.json
    at new NodeError (node:internal/errors:372:5)
    at throwExportsNotFound (node:internal/modules/esm/resolve:440:9)
    at packageExportsResolve (node:internal/modules/esm/resolve:664:7)
    at resolveExports (node:internal/modules/cjs/loader:482:36)
    at Function.Module._findPath (node:internal/modules/cjs/loader:522:31)

    at Object.<anonymous> (C:\Users\marye\onedrive\desktop\athenae server\index.js:4:14) {
  code: 'ERR_PACKAGE_PATH_NOT_EXPORTED'
}

Steps to reproduce the error:

const ipfs = require("ipfs")
const node = ipfs.create()

我在使用ipfs-core这个库时遇到了同样的问题，我的解决办法是降低库的版本

Same error here,
(node 16.15.1 LTS)

test.ts

import {create} from 'ipfs-core'

create().then((ipfs) => {
  ipfs.add('Hello world').then((cid) => {
    console.info(cid)
  })
})

my workaround is to modify ipfs-core/package.json

  "exports": {
    ".": "./src/index.js",
    "./config/profiles": {
      "import": "./src/components/config/profiles.js"
    }
  },

@ki4jgt : You'll need to update to use ESM. See https://github.com/ipfs/js-ipfs/blob/master/docs/upgrading/v0.62-v0.63.md#esm

@eltorio : Please change your typescript configuration to produce ESM not CJS.

@BigLep, I'm a little out of touch with that process. Can you show me how? I watched a video on YouTube, on importing, but with the node_modules folder, where am I pointing exactly?
