React Native 是一个用于构建跨平台移动应用的框架，它允许开发者使用 JavaScript 编写一次代码，然后在 iOS、Android 和 Web 平台上运行。以下是使用 React Native 开发软件的步骤：
1. 安装 Node.js 和 npm：首先，你需要在你的计算机上安装 Node.js 和 npm（Node.js 包管理器）。你可以从官网下载并安装：https://nodejs.org/en/download/
2. 安装 Android Studio：Android Studio 是 Google 官方推荐的 Android 开发工具，你需要下载并安装。你可以在官网下载并安装：https://developer.android.com/studio
3. 安装 Xcode：Xcode 是 Apple 官方推荐的 iOS 开发工具，你需要下载并安装。你可以在官网下载并安装：https://developer.apple.com/xcode/
4. 创建一个新的 React Native 项目：打开 Android Studio，点击 "Create New Project"，选择 "Empty Activity"，然后点击 "Next"。在 "Project Name" 中输入你的项目名称，在 "Package name" 中输入你的项目包名，在 "Minimum API level" 中输入你的最低 API 级别，然后点击 "Finish"。
5. 安装必要的依赖：在你的项目目录下，运行以下命令来安装必要的依赖：
```bash
npm install react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native.
