react-native-maps导入报错：Requiring unknown module "undefined"求助

Let’s walk through the most reliable fixes for this frustrating module resolution issue:

• Confirm react-native-maps is properly installed
  First, check your package.json to see if react-native-maps is listed under dependencies. If it’s missing, install it with your package manager:

  # Using npm
  npm install react-native-maps --save
  
  # Using yarn
  yarn add react-native-maps
  

• Restart Metro Bundler with cache cleared
  This is the go-to fix for most module-related glitches. Stop your running Metro server, then restart it with a full cache reset:

  npx react-native start --reset-cache
  

  After that, reload your app (shake the device/emulator and tap "Reload" or press R twice in the terminal for Android emulators).

• Ensure proper linking (especially for older React Native versions)
  If you’re on React Native < 0.60, auto-linking isn’t enabled—you’ll need to link the module manually:

  npx react-native link react-native-maps
  

  For iOS, even with auto-linking, sometimes you need to refresh pods:

  cd ios && pod install && cd ..
  

• Double-check your import statement
  Make sure there are no typos in your code. The correct import line should be:

  import MapView from 'react-native-maps';
  

  Avoid extra spaces or misspellings here—small typos can cause big issues.

• Reinstall dependencies as a last resort
  If nothing else works, delete your node_modules folder and reinstall everything to rule out corrupted installs:

  rm -rf node_modules && npm install # or yarn install
  

  Then repeat the cache-cleared Metro restart step.
