Hi! I'm trying to run GraphQL Playground like says in https://github.com/graphcool/graphql-playground#development . But when I run these commands the next error is prompted:

./node_modules/react-codemirror/node_modules/react-dom/lib/ReactNodeTypes.js
Module not found: Can't resolve 'react/lib/React' in '/home/miguel/Documentos/TESTS/graphql-playground/packages/graphql-playground-react/node_modules/react-codemirror/node_modules/react-dom/lib'

Am I doig something wrong? Any ideas? Thanks in advance
