我正试图在设备上运行我的第一个React Native应用程序，但构建总是失败，并出现以下错误：

未找到React目录错误
前面的几件事：
该项目在XCode模拟器上运行良好。
我正在使用cocoapods，并试图从xcWorkspace而不是项目运行构建(尽管目标的完整路径是/Users/XXXX/Nigh/ReactNativeNigh/Nigh/ios/Nigh.xcodeproj，这让我有点困惑(。
我已经移除并重新安装了节点模块，链接并完成了新的pod安装。
看起来我所要做的就是将React添加到Debug iphoneos文件夹中，但我不确定如何做到这一点，也不确定这是否是解决方案。我的第一次尝试是确保React符合该计划的构建目标。它是列表中第一个勾选了所有框的，但出于某种原因，它说React(缺失(。根据React Native/Xcode Upgrade和现在找不到RCTConvert.h，我从Targets列表中删除了React(缺少(，并试图再次添加React，但React甚至没有出现在列表中。此外，Pods/Products文件夹显示的libReact.a与其他.a文件不同，没有Archive(？(图标：

这是podfile:

我注释掉了if target.name=="React"块，但无论哪种方式都会出现错误。
我认为问题是React不在该计划的构建目标中，这是对的吗？如果是，有人知道如何将其包括在内吗？如果没有，有人知道真正的原因是什么/如何解决/解决吗？
我认为您的问题来自use_frameworks!，请尝试删除该行，再次删除DerivedData、Pods、xcworkspace、Podfile.lock和pod install。
上个月我在升级RN版本时遇到了这个问题。这件愚蠢的事情花了我1周的时间才知道问题，花了20分钟才解决。
希望这能帮助
