React Native: Build Missing iOS + Android folders

Question

I recently update my React Native + React dependencies. I then removed by iOS + android folders to create fresh ones, but the following command that used to work in the past is now giving an error

Dependencies:

• React (16.11.0)
• React Native (0.61.2)

What worked in the past:

react-native upgrade --legacy true

Error:

error: unknown option `--legacy'

What I've tried

• I've even tried using just one dash too with -legacy
• react-native upgrade (Doesn't work since I'm on the latest version of React Native)

Answer 1

You can create new iOS/Android folder using react-native-eject,

Follow this steps,

1. Remove old iOS/Android folder from Projects
2. Install @react-native-community/cli (npm i @react-native-community/cli)
3. Install react-native-eject (npm i react-native-eject)
4. Run this command for generate new iOS/Android folders npx react-native eject
