Answer 1

The error appears due to the renaming of schedule/tracking to schedule/tracing from react@16.5.1 to react@16.5.2.

The issue is resolved by choosing the correct version of react for your react-native version:

• RN <= 0.57.2 --> react <= 16.5.1
  • Be sure to lock your react version in this case. Your package.json should look like this: react@16.5.1. Check that there isn't any ^ before the version.
  • (having react@^16.5.1 in your package.json may resolve to a react version >= 16.5.1, which will NOT work)
  • example command: yarn add react@16.5.1
• RN >= 0.57.3 --> react >= 16.6
  • example command: yarn add react@16.6.0

For further Information you can check the Github Issue #21150 and Github Issue #21140.

Sidenote for Expo Users:

If you are using expo, be aware that expo <= 32.0.0 uses a react-native version <= 0.57.2 and therefore will require the react version to be <= 16.5.1

If it does not work immediately

Try to reset the cache of your packager before continuing: yarn start --reset-cache
