Module build failed (from ./node_modules/babel-loader/lib/index.js): Error: Cannot find module 'babel-preset-react'

Question

I'm stuck with the following error when trying to build a react app with Webpack4 and Babel7.

ERROR in ./src/index.js Module build failed (from ./node_modules/babel-loader/lib/index.js): Error: Cannot find module 'babel-preset-react' from '/Users/me/Desktop/reflask' - If you want to resolve "react", use "module:react" - Did you mean "@babel/react"? at Function.module.exports [as sync] (/Users/me/Desktop/reflask/node_modules/resolve/lib/sync.js:43:15) at resolveStandardizedName (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/files/plugins.js:101:31) at resolvePreset (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/files/plugins.js:58:10) at loadPreset (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/files/plugins.js:77:20) at createDescriptor (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:154:9) at items.map (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:109:50) at Array.map () at createDescriptors (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:109:29) at createPresetDescriptors (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:101:10) at passPerPreset (/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:58:96) @ multi (webpack)-dev-server/client?http://localhost:8080 ./src main[1]

I've tried removing the node_modules folder and reinstalling dependencies with the following.

Terminal

rm -rf node_modules/
npm install

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './js/components/App.jsx';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();

.babelrc

{
  "presets": ["@babel/preset-env", "@babel/preset-react"]
}

Answer 1

in your webpack config did you already try @babel/preset-react instead of just react?

Btw. you test for /\.js$/ Better test for /\.jsx?$/ (x? means x is optional), because you import a .jsx file in your index.js

Not

options: {
    presets: ['react']
}

but

options: {
    presets: ['@babel/preset-react']
}

Answer 2

place .babelrc file at root dir with this inside

{
  "presets": ["@babel/preset-env", "@babel/preset-react"]
}

and remove preset from babel-loader webpack cfg

options: {
  presets: ['react']
}

Answer 3

I did it at the end with this settings, (becouse es2015 has been changed https://www.npmjs.com/package/babel-preset-es2015) now!

And presets in package.json or .babelrc or babel.config ::

use: {
                  loader: 'babel-loader',
                  options: {
                      presets: ['@babel/react', '@babel/preset-env'],
                          plugins: ['@babel/plugin-proposal-class-properties']
                  }
              }

and..

"devDependencies": {
    "@babel/cli": "^7.1.5",
    "@babel/core": "^7.1.6",
    "@babel/plugin-proposal-class-properties": "^7.1.0",
    "@babel/plugin-transform-react-constant-elements": "^7.0.0",
    "@babel/plugin-transform-react-inline-elements": "^7.0.0",
    "@babel/preset-env": "^7.1.6",
    "@babel/preset-react": "^7.0.0",
    "@babel/register": "^7.0.0",
    "@babel/runtime": "^7.1.5",
    "babel-eslint": "^8.2.6",
    "babel-loader": "^8.0.4",
    "babel-node": "^6.5.3",
    "babel-plugin-react-transform": "^3.0.0",
    "babel-plugin-transform-class-properties": "^6.24.1",
    "babel-plugin-transform-react-pure-class-to-function": "^1.0.1",
    "babel-plugin-transform-react-remove-prop-types": "^0.4.20",
    "babel-polyfill": "^6.26.0",
    "babel-preset-env": "^1.7.0",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "webpack": "^4.26.1"
  }

and the code that you call to preset example:

   "theme:build": "babel theme/src -d theme/dist --presets @babel/react --plugins transform-class-properties --quiet && npm run webpack:store",

presets @babel/react

in github very much forum about the subject!
