Webpack / Babel / React Error: "Unknown parameter: foo / node_modules / react / react.js.Children"

Question

I am trying to create a project using webpack and will respond to this webpack configuration:

var path = require('path'); var webpack = require('webpack'); module.exports = { entry: [ 'babel-polyfill', './app/less/main.less', './app/main.js', 'webpack-dev-server/client?http://localhost:8080' ], output: { publicPath: '/', filename: 'dist/main.js' }, debug: true, devtool: 'source-map', module: { loaders: [ { test: /\.js$/, include: path.join(__dirname, 'app'), loader: 'babel-loader', query: { presets: ['react', 'es2015'] } }, { test: /\.less$/, loader: "style!css!autoprefixer!less" }, ] } }; 

I am sure that I also have pm modules, and I have webpack installed, however when I start webpack I get:

 Module build failed: ReferenceError: [BABEL] /Users/me/foo/app/main.js: Unknown option: foo/node_modules/react/react.js.Children 

Any ideas?

Answer 1

Sorry, I forgot to install babel-preset-react

Answer 2

I had this problem only yesterday. Drop include: fixed.
