React Native Build Error:无法读取优化配置文件(即使在更改优化配置之后)

Question

我试图通过此视频中的步骤解决一些配置问题,之后构建过程会报告错误.

该视频中的步骤如下: 1. project -> clean 2. project -> build 3. project -> perform action -> Generate Optimization File 4. Enable 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:

Could not read profile [My Project Folder]/node_modules/react-native/React/OptimizationProfiles/React.profdata: No such file or directory

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

优化级别适用none于所有目标:
来源于此

2. 手动将优化配置文件的路径设置为另一个位置(没有生成profdata文件btw,这是另一个错误,但它在连接的设备上运行应用程序)

3. DerivedData按照此问题的答案中的建议删除文件夹

4. 删除Build文件夹
5. 清除Xcode首选项并重新安装Xcode

每当我构建它仍然试图找到文件/node_modules/react-native/React/OptimizationProfiles/React.profdata.使用时结果相同react-native run-ios.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:

尝试其他方法的想法？谢谢

Answer 1

找到了解决方案（但需要一定程度的重复设置工作），如果您遇到相同的问题并且问题中列出的方法均无效，您可以尝试此操作（作为最后的手段）：

失败后我查看了登录终端，react-native run-ios出现以下错误：

Error: Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier 
build/Build/Products/Debug-iphonesimulator/SomeProject.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist  

正如这里所建议的，react-native upgrade（反应原生版本是0.47.2），为了确保所有缓存都被清理，我也按照这个线程中提到的那样做了：

watchman watch-del-all
rm -rf $TMPDIR/react-*
rm -rf yarn.lock
rm -rf ./node_modules
yarn install

在这些步骤之后，剩下的基本上就是再次设置项目，我做了react native link以及 React Native 插件的所有其他配置（例如更新 info.plist）。但之后项目就可以成功构建了。

我不确定这是否是 Xcode 或 RN 中的错误（在我使用之后perform action -> generate optimization file），它一直试图找到那个/node_modules/react-native/React/OptimizationProfiles/React.profdata奇怪的文件。

希望这可以帮助。
