Error: Cannot find module ‘@react-native/metro-config’
When you encounter the error “Cannot find module ‘@react-native/metro-config'”, it means that your project is missing the required module for React Native Metro configuration.
Possible Causes:
- The required module is not installed
- A version mismatch between the required module and your project
- Incorrect configuration or missing dependencies
Solution:
To resolve this error, you can follow these steps:
1. Verify package.json:
Check if the ‘@react-native/metro-config’ module is listed as a dependency in your project’s package.json file.
{
"dependencies": {
"@react-native/metro-config": "^x.y.z",
...
},
...
}
Make sure to replace ‘x.y.z’ with the specific version you want to use or the one that your project requires.
2. Install missing module:
If the module is missing, you need to install it by running the following command:
npm install @react-native/metro-config@x.y.z
Replace ‘x.y.z’ with the version number specified in your package.json file.
3. Clean project cache (optional):
If you have installed the module but the error still persists, you can try cleaning the project cache by using:
npx react-native start --reset-cache
4. Verify React Native version compatibility:
Make sure that the version of ‘@react-native/metro-config’ is compatible with the React Native version used in your project. Check the module’s documentation or the React Native upgrade guide for compatibility information.
5. Restart Metro Bundler:
Try restarting the Metro Bundler and rebuilding your project:
npx react-native start
npx react-native run-android (or run-ios)
Example:
If your project’s package.json file looks like this:
{
"dependencies": {
"@react-native/metro-config": "^0.64.2",
...
},
...
}
You need to run the following command to install the module:
npm install @react-native/metro-config@0.64.2
Then, restart the Metro Bundler and rebuild your project.
