The error appears due to the renaming of schedule/tracking to schedule/tracing from [email protected] to [email protected].

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: [email protected]. 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 [email protected]
• RN >= 0.57.3 --> react >= 16.6
  • example command: yarn add [email protected]

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

If running with your versions of npm packages:

react: 16.0.0 => 16.0.0 
react-native: ^0.57.3 => 0.57.3

We'll have the same error as below:

error: bundling failed: Error: Unable to resolve module `scheduler/tracing` from 
`C:\projects\rnw\node_modules\react-native\Libraries\Renderer\oss\ReactNativeRenderer- 
dev.js`: Module `scheduler/tracing` does not exist in the Haste module map

Upgrade to the following versions:

"dependencies": {
  "react": "16.6.3",
  "react-native": "0.58.1"
},

And the error will be gone.

If there is an error related to module Schedule/tracking not found, use react-native 0.55.0 version. Above RN->0.55.0 version schedule/tracking package is renamed or moved to another module which is not found by node server.

Command: react-native init (Project Name) --version 0.55.0
