🐛 wrong babel usage

I don’t know is that a bug report or my mistake, but whole day today I’m struggling and get different behavior from time to time.

This is my .babelrc

{
  "presets": [
    "env",
    "stage-1",
    "react"
  ],
  "plugins": ["transform-react-jsx"],
  "ignore": [
    "node_modules"
  ]
}

and this is the message what I see

Server running at http://localhost:1234

that happens when I use react-dropzone package. Looks like that parcel/babel transpile node_modules as well?

here is my package.json

  "dependencies": {
    "prop-types": "15.6.0",
    "react": "16.1.0",
    "react-dom": "^16.2.0",
    "react-dropzone": "4.2.3",
    "react-pdf": "2.5.2"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-plugin-add-module-exports": "0.2.1",
    "babel-plugin-transform-react-jsx": "^6.24.1",
    "babel-preset-env": "^1.6.1",
    "babel-preset-react": "6.24.1",
    "babel-preset-stage-1": "6.24.1",
    "cross-env": "^5.1.1",
    "enzyme-adapter-react-16": "^1.1.0",
    "eslint": "4.14.0",
    "eslint-config-airbnb": "16.1.0",
    "eslint-plugin-import": "2.8.0",
    "eslint-plugin-jsx-a11y": "6.0.3",
    "eslint-plugin-react": "7.5.1",
    "jest": "^21.2.1",
    "node-sass": "^4.7.2",
    "parcel-bundler": "^1.1.0",
    "prettier": "^1.9.1"
  }

as soon as I don’t use that package everything is ok.

 parcel --version
1.4.1

In v1.6.0, we no longer transpile node_modules by default. Closing.

I’ve also encountered this problem. Im trying to create some starter app with react and material-ui. With the latest version parcel is working great. But when I want to use material-ui@next the problem with babelrc shows up. There are multiple packages in nodemodules that contains Babelrc file which parcel tries to ctranspile and this is causing crash preventing my app to run. After deleting all Babelrc files from modules app successfully starts up bit then there are some problem with importing components from material-ui 😦
