React 0.14 error: Module build failed: ReferenceError: [BABEL] .../node_modules/eslint-loader/index.js!/.../main.jsx: Unknown option: base.stage

Question

This is my package.json:

  "scripts": {
    "test": "echo \"Error: no test specified\n\" && exit 1",
    "lint": "npm run lint-js && npm run lint-css",
    "lint-js": "echo \"\\033[33mLinting JS\\033[0m\n\" && eslint . --ext .js --ext .jsx",
    "lint-css": "echo \"\\033[33mLinting CSS\\033[0m\n\" && csslint app/style --quiet",
    "start": "echo \"\\033[33mStarting dev server at localhost:8080\\033[0m\n\" && TARGET=dev webpack-dev-server --devtool eval-source --progress --colors --hot --inline --history-api-fallback",
    "compile": "echo \"\\033[33mBuilding for production\\033[0m\n\" && TARGET=build webpack -p",
    "build": "npm run lint-js && npm run lint-css && npm run compile"
  },
  "private": true,
  "dependencies": {
    "alt": "^0.17.8",
    "babel-core": "^6.1.2",
    "babel-loader": "^6.1.0",

    "webpack": "^1.12.3",
    "webpack-dev-server": "^1.12.1",
    "webpack-merge": "^0.2.0"
  }
}

This is the complete error message, I read that this error can be solved using babelify so I added it, although I don't need it.

ERROR in ./app/

It all started when I wanted to upgrade to React 0.14, and ended up installing all the packages one by one.

Answer 1

You will need to have installed:

• babel-core
• babel-loader
• babel-preset-es2015
• babel-preset-react
• babel-preset-stage-0

Your dependencies in your package.json would be:

{
  "name": "react-transform-example",
  "devDependencies": {
    "babel-core": "^6.0.20",
    "babel-loader": "^6.0.1",
    "babel-preset-es2015": "^6.0.15",
    "babel-preset-react": "^6.0.15",
    "babel-preset-stage-0": "^6.0.15",
    "express": "^4.13.3",
    "webpack": "^1.9.6"
  },
  "dependencies": {
    "react": "^0.14.0",
    "react-dom": "^0.14.0"    
  }
}

And your .babelrc file

{
  "presets": ["es2015", "stage-0", "react"]
}

More info at setting-up-babel-6

Answer 2

You're using babel 6 which doesn't have a stage option anymore, instead you have to use presets, e.g:

http://babeljs.io/docs/plugins/#presets

http://babeljs.io/docs/plugins/preset-stage-0/

Installation

$ npm install babel-preset-stage-0

Usage

Add the following line to your .babelrc file:

{"presets": ["stage-0"] }

Note you'll also need the es2015 and react preset. Also note that at least some of the hot reloading plugins are not compatible yet.
