Actually I am using react-native-camera in my app but it is not working in this version (react-native: 0.56.0) & its working in this version(react-native: 0.55.4).
So now I want to downgrade the react-native: 0.56.0 to react-native: 0.55.4.
My System configuration: npm 6.1.0, react-native-cli: 2.0.1, react-native: 0.56.0, Mac OS, Xcode 9.3
Thank you
So open the file of your project named as package.json
Inside it you can find react-native": "0.56.4" replace this version with react-native": "0.55.4" or whatever the version you want
Then save the file
Go to the terminal or power sell
Rich to your project directory and run the command npm install
After installation check the version of react-native by running the command react-native --version and make sure that version is which you changed in package.json
Restart your project and you are ready to go
