Jest fails to work with Babel7

🐛 Bug Report

A clear and concise description of what the bug is. I have a simple project where I’m using Babel 7.0.0 instead of 6. Jest fails to work with it, saying that it can’t find the “env” preset, even thought it is installed and indicated in the package-based config.

To Reproduce

Steps to reproduce the behavior: My package.json:

  "scripts": {
    "test": "jest --coverage --no-cache"
  },
  "babel": {
    "presets": [
      "env"
    ]
  },
  "devDependencies": {
    "@babel/core": "^7.0.1",
    "@babel/preset-env": "^7.0.0",
    "babel-jest": "^23.6.0",
    "jest": "^23.6.0",
    "regenerator-runtime": "^0.12.1"
  }

Expected behavior

Expect the test to run. When I down grade to Babel 6.x it works as expected. When I try to use Babel 7, it fails.

A clear and concise description of what you expected to happen. When I run npm t I get the following error:

● Test suite failed to run

    Couldn't find preset "env" relative to directory "/Users/rbiggs/Desktop/jest-test"

      at node_modules/babel-core/lib/transformation/file/options/option-manager.js:293:19

Actually, this is the package setup that got this working for me:

  "devDependencies": {
    "@babel/core": "^7.0.1",
    "@babel/preset-env": "^7.0.0",
    "babel-core": "^7.0.0-bridge.0",
    "babel-jest": "^23.6.0"
}

@yvele Because Jest uses babel-core, which is still v6. To use v7, you need to use the bridge which pipes babel-core (v6) to @babel/core (v7) internally.
