Finally, install cocoapods by running:

sudo gem install cocoapods

Install Homebrew

Homebrew is a package manager for macOS. When it needs to install software from third-party websites. To install it, run:

ruby -e "$(curl -fsSL"

Install Watchman

React Native uses watchman to detect real-time code changes and it automatically builds and pushes the update to your device without manually refreshing.

brew install watchman

Install Java JRE and JDK

There is a risk of react-native build failure if you don’t have a complete installation of Java. Downloading Android Studio is not enough since it comes bundled with its own JRE.

brew install --cask adoptopenjdk/openjdk/adoptopenjdk8

Install React Native

With React Native, you can write an application in Javascript and then the React Native Compiler will convert your Javascript code into native code for iOS and Android environments. React Native command line interface can be installed using npm as below.

npm install -g react-native-cli
