## System Requirements <a href="#system-requirements" id="system-requirements"></a>

### NodeJS

Make sure you have a recent version (8.11 or later) of [Node](https://nodejs.org/en/) installed globally.

We recommend installing Node and Watchman using [Homebrew](http://brew.sh/). 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](https://facebook.github.io/watchman) is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.

### **Yarn (**&#x72;ecommend) <a href="#yarn-recommend" id="yarn-recommend"></a>

‌

Please follow yarn official install guide.‌

​<https://yarnpkg.com/en/docs/install#mac-stable>​‌

### **React Native Developer Tools** <a href="#react-native-developer-tools" id="react-native-developer-tools"></a>

‌

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** <a href="#expo-cli" id="expo-cli"></a>

‌

Assuming that you have [Node 10+](https://nodejs.org/en/download/) 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 <a href="#xcode" id="xcode"></a>

‌

The easiest way to install Xcode is via the [Mac App Store](https://itunes.apple.com/us/app/xcode/id497799835?mt=12). 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.![](https://facebook.github.io/react-native/docs/assets/GettingStartedXcodeCommandLineTools.png)Xcode Command Line Tools
