Unable to resolve dependency tree with React 18/Next.js

[Vicente Matus]

I'm starting a project with Next.js
npx create-next-app my-project

Then i install
npm i little-state-machine

But when i try to install little-state-machine-devtools i have the problem

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

This is my package.json:

{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "dependencies": {
    "next": "12.1.6",
    "react": "18.1.0",
    "react-dom": "18.1.0"
  },
  "devDependencies": {
    "eslint": "8.15.0",
    "eslint-config-next": "12.1.6"
  }
}

How can i solve this with React 18/Next.js?

@bluebill1049 is there anyway you check this?, i'm having peer dependency problems with React 18

Here's a PR that should work for react 17 & possibly 18:

Thanks, but i already changed solutions. It broke many of my projects that used little-state-machine package 😢
