我安装了 CocoaPods 并在 Xcode 中打开了 xcworkspace，但在尝试构建时出现此错误：

复制

设法用一个新项目重现它：

    react-native init react-native run-ios（运行正常） pod init &amp;&amp; pod install（未添加依赖项） 从 XCode（或 react-native run-ios）构建

这是一个示例项目（只需运行 npm install 和 react-native run-ios 即可使用此示例项目重现） CocoaPodsFailure.zip

附加信息

React Native 版本：0.36.1 平台：iOS 操作系统：MacOS

【问题讨论】：

您使用的是哪个版本的 xcode？这可能是个问题。 【参考方案1】：

遇到了同样的问题。在我找到建议添加该行的帖子之前尝试了各种方法：

使用框架

到您的 PodFile。它使我能够克服链接错误。

以上是关于让 CocoaPods 与 React Native 一起工作的问题的主要内容，如果未能解决你的问题，请参考以下文章

React Native 使用 Cocoapods

CocoaPods 找不到 pod "React/Core" 的兼容版本

无法在 CocoaPods 中安装 React 子规范

Cocoapods 总是安装旧的 React (0.11.0)

在 codepush 和 cocoapods 中找不到 React/RCTEventEmitter.h
