ios - 无法运行 ios 的 React Native 项目

Question

我正在开发React Native应用程序，我是React-Native新手，首先我曾在Android平台上工作并成功构建了apk文件。 现在我想使用我的 macbook 中的命令 react-native run-ios 运行 ios 版本，但它会引发错误:

注意:从一开始我就在 MacBook 上开发了这个应用程序

user-MacBook-Pro:myApp user$ react-native run-ios
error Cannot read property 'podfile' of null. Run CLI with --verbose flag for more details.
TypeError: Cannot read property 'podfile' of null

end

请知道解决办法的人帮帮我。 提前致谢。

Answer 1

1. 打开终端
2. 将 ios 文件夹移动到 React-Native 项目下
3. 运行pod install命令 - 这将为已安装的需要链接的 rpm 模块安装所有链接库。
4. 之后运行react-native run-ios或双击projectName.xcworkspace，这将打开Xcode。
5. 选择要运行和播放项目的设备。
