I am also facing a same issue while running the react-native app. The version i am using is as follows:

React-Native:0.57.1 react-native-cli:2.0.1 node:v8.11.3 npm:5.6.0

Babel Version details:

"devDependencies": { "@babel/runtime": "^7.0.0", "babel-jest": "20.0.3", "babel-preset-react-native": "^2.1.0", "jest": "20.0.4", "react-test-renderer": "16.0.0-alpha.12", "schedule": "^0.4.0" }, "jest": { "preset": "react-native" } }

Error:

I was using babel-preset-react-native in dependency which has been deprecated instead "metro-react-native-babel-preset": "^0.47.0" is now being used. So, I updated this in .babelrc file and I added the below line:

{
  "presets": ["module:metro-react-native-babel-preset"]
}

The above code resolved the issue.
