peer invalid: @babel/core@7.0.0-beta.38

Do you want to request a feature or report a bug? Bug. It affects React Native too https://github.com/facebook/react-native/issues/18490

What is the current behavior? Can not generate npm-shrinkwrap.json file. With command npm ls @babel/plugin-check-constants@7.0.0-beta.38 I discovered that problem is in metro bundler package

└─┬ react-native@0.54.2
  └─┬ metro@0.28.0
    ├── UNMET PEER DEPENDENCY @babel/core@7.0.0-beta.42
    └── @babel/plugin-check-constants@7.0.0-beta.38

If the current behavior is a bug, please provide the steps to reproduce and a minimal repository on GitHub that we can yarn install and yarn test. Create new React Native app via react-native init, install node packages and run npm shrinkwrap command

What is the expected behavior? Generated npm-shrinkwrap.json file

Please provide your exact Metro configuration and mention your Metro, node, yarn/npm version and operating system. Environment: OS: Linux 4.4 Node: 6.13.1 Yarn: Not Found npm: 3.10.10 Watchman: 4.9.0 Xcode: N/A Android Studio: 3.0 AI-171.4443003

Hi!

Thanks for the heads up here! babel-beta.38 is being installed due to babel-preset-fbjs. It seems that with babel@7 stable @babel/plugin-check-constants is not needed anymore so we’re going to remove it from the corresponding package 😄
