Seems you're trying to access 'ReactNative.Component' from the 'react-native' package. Perhaps you meant to access 'React.Component' from the 'react' package instead? For example, instead of: import React, { Component, View } from 'react-native'; You should now do: import React, { Component } from 'react'; import { View } from 'react-native'; Check the release notes on how to upgrade your code - https://github.com/facebook/react-native/releases/tag/v0.25.1
