System Requirements

NodeJS

Make sure you have a recent version (8.11 or later) of Node installed globally.

We recommend installing Node and Watchman using Homebrew. Run the following commands in a Terminal after installing Homebrew:

brew install node
brew install watchman

If you have already installed Node on your system, make sure it is Node 8.3 or newer.

​Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.

Yarn (recommend)

‌

Please follow yarn official install guide.‌

React Native Developer Tools

‌

Node comes with npm, which lets you install the React Native command line interface.‌

Run the following command in a Terminal:

npm install -g react-native-cli

If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh.

‌

Or with yarn

yarn global add react-native-cli

‌

Note: (Ubuntu) make sure you add ~/.yarn/bin to your PATH‌

Expo CLI

‌

Assuming that you have Node 10+ installed, you can use npm to install the Expo CLI command line utility:

npm install -g expo-cli

‌

Or with yarn

yarn global add expo-cli

‌

Xcode

‌

The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.‌

If you have already installed Xcode on your system, make sure it is version 9.4 or newer.‌

Command Line Tools‌

You will also need to install the Xcode Command Line Tools. Open Xcode, then choose "Preferences..." from the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.Xcode Command Line Tools
