On postinstall jest-babel-preprocessor will update the dependent package's package.json to add jest.scriptPreprocessor & jest.unmockedModulePathPatterns fields if they do not exist.

i.e.:

in your package.json set the jest.scriptPreprocessor field:

{
  "jest": {
    "scriptPreprocessor": "<rootDir>/node_modules/jest-babel-preprocessor/preprocessor.js"
    "unmockedModulePathPatterns": [
      "<rootDir>/node_modules/react"
    ]
  }
}
