ios - react native 构建错误 : Could not read optimization profile file (even after change optimization configuration)

Question

我试图通过此 video 中的步骤解决一些规定问题，之后构建过程不断报告错误。

该视频中的步骤是:
1.项目->清理
2.项目->构建
3.项目->执行 Action ->生成优化文件
4.启用优化


它确实帮助我在连接的设备上运行该应用程序。但在此之后，构建过程不断失败，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 SO 上看了几个小时之后，我尝试了以下不同的方法，但都没有奏效:
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都是none:
source here

1. 手动将优化配置文件的路径设置到另一个位置(顺便说一句，没有生成 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)

2. 按照 answers to this question 中的建议删除 DerivedData 文件夹

3. 删除构建文件夹
4. 清除 Xcode 首选项并重新安装 Xcode

每当我构建它时，它仍在尝试在 /node_modules/react-native/React/OptimizationProfiles/React.profdata 中查找文件。使用 react-native run-ios 时结果相同。它是某种缓存吗？(虽然我删除了 DerivedData 文件夹、Build 文件夹，然后清理了项目)。以下是错误消息的更多信息:

有没有其他尝试方法的想法？谢谢

找到了解决方案(但它需要一定程度的重复设置工作)，如果您遇到同样的问题并且问题中列出的方法均无效，您可以试试这个(作为最后的手段):

在 react-native run-ios 失败并出现以下错误后，我查看了登录终端:

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

按照建议here , react-native upgrade (react-native version is 0.47.2), 为了确保所有的缓存都被清理了，我也是按照this thread中提到的那样做了这个:

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

完成这些步骤后，剩下的基本上就是重新设置项目，我做了 react native link 和 react native 插件的所有其他配置(例如更新 info.plist)。但是该项目可以成功构建。

我不确定它是否是 Xcode 或 RN 中的错误(在我使用 perform action -> generate optimization file 之后)它一直试图找到该文件 /node_modules/react-native/React/OptimizationProfiles/React.profdata 这很奇怪。

希望这对您有所帮助。
