Errors so far:

warn Your project is using deprecated "rnpm" config that will stop working from next release. Please use a "react-native.config.js" file to configure the React Native CLI. Migration guide: https://github.com/react-native-community/cli/blob/master/docs/configuration.md
warn Package react-native-firebase has been ignored because it contains invalid configuration. Reason: Unknown option dependency.platforms.android.buildPatch with value "" implementation project(':react-native-firebase')"" was found. This is either a typing error or a user mistake. Fixing it will remove this message.
warn The following packages use deprecated "rnpm" config that will stop working from next release:
  - react-native-maps: https://npmjs.com/package/react-native-maps
  - rn-fetch-blob: https://npmjs.com/package/rn-fetch-blob
  - tipsi-stripe: https://github.com/tipsi/tipsi-stripe#readme
Please notify their maintainers about it. You can find more details at https://github.com/react-native-community/cli/blob/master/docs/configuration.md#migration-guide.
error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
  - react-native-ble-plx (to unlink run: "react-native unlink react-native-ble-plx")
  - react-native-keep-awake (to unlink run: "react-native unlink react-native-keep-awake")
  - react-native-sound (to unlink run: "react-native unlink react-native-sound")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.
