ios – React Native Build Error：无法读取优化配置文件(即使在

该视频中的步骤如下：

1.项目 – >清洁
2.项目 – >建立
3.项目 – >执行操作 – >生成优化文件
4.启用Optimazation
?

它确实帮助我在连接的设备上运行应用程序.但在此之后,构建过程始终失败,并显示以下错误消息：

无法读取配置文件[我的项目文件夹] /node_modules/react-native/React/OptimizationProfiles/React.profdata：没有这样的文件或目录

在环顾SO几个小时后,我尝试了以下不同的方法,但没有一个工作：
1)

Go to Project -> Build Setting -> Apple LLVM 9.2-code generation  
clear Optimization Profile File // clear is removing the value to empty,correct?  
Clean project and build again

所有目标的优化级别均为无：

>手动将优化配置文件的路径设置为另一个位置(没有生成的profdata文件,这是另一个错误,但它在连接的设备上运行应用程序)
>按照answers to this question中的建议删除DerivedData文件夹
>删除Build文件夹
>清除Xcode首选项并重新安装Xcode

每当我构建它仍然试图在/node_modules/react-native/React/OptimizationProfiles/React.profdata中找到文件.使用react-native run-ios时的结果相同.它是某种缓存吗？(虽然我删除了DerivedData文件夹,构建文件夹,并清理了项目).这里是更多错误信息的信息：
