package.json dependency issue? - "Uncaught ReferenceError: react is not defined"

I'm running into an issue where my build works fine on master branch, but on a sub-branch it is producing an error of "Uncaught ReferenceError: react is not defined". The package.json for both branches are a little different, but I'm still unsure why the sub-branch is showing that error as React is listed as a dependency for both.

on master-branch react is defined as "devDependency", but on sub-branch as "dependency". I belive on sub-branch it also should be defined as "devDependency"

what is my wrong?
my OS is macOS highSierra version 10.13.3 node js version 10 react version 16.2
nodejs version 10
webpack version 4
npm version 6.0.1
but couldn't find preset "#babel/env"
How to solve this problem???

This is the problem with your presets definition in your .babelrc. The correct preset name is preset-env, not env.
Update your .babelrc from #babel/env to #babel/preset-env will solve the problem.

Preact.js - How to start a auto re run server like React.js does

I would like to use a development server just like React does with npm start. But, with Preact when I use the same command it opens a static server and I have to restart it manually each time when I want to see some change in my project.

Use the dev script instead?
$ npm run dev
Your start script is doing serve build -s -c 1. React CRA's start script will boot up a webpack dev server which is what your dev script is doing.
npm start is short for npm run start. npm run <command> is just a small proxy that looks up the different commands you have listed in package.json.
Read more about npm scripts here.

Eslint - eslint-config-airbnb not find

I'm getting some errors module eslint-config-airbnb not found, when run command eslint **/*.jsx.

Check to see if your eslint has been installed / installed correctly.
Also reinstall your node_modules folder as well, if eslint has been configured.
Since eslint isn't in your devDependencies, I assumed you've got it set up globally?
I've copied your package.json set up, but tested it with a local eslint and it's working for me.

npm install -D rimraf prettier babel-eslint eslint-plugin-react eslint-plugin-jsx-a11y eslint-plugin-import eslint-config-prettier eslint-config-airbnb eslint-plugin-react-hooks
npm run build
Try running this, worked for me.
