To Reproduce Steps to reproduce the behavior:

1. npx -p @storybook/cli sb init --type react -f ERROR in ./.storybook/config.js Module build failed (from ./node_modules/babel-loader/lib/index.js): Error: Cannot find module ‘babel-core’ at Function.Module._resolveFilename (module.js:547:15) at Function.Module._load (module.js:474:25) at Module.require (module.js:596:17) at require (internal/module.js:11:18)

If you use "babel-loader": "^7.1.5", you should add babel-core yourself.

Upgrade to “babel-loader”: “^8”, to use the @babel/core
