xcode 'boost/config/user.hpp' file not found

Question

I'm using Xcode 9, everything was fine. but after I upgrade my React-native version to 0.46, and upgrade my React to 16.0.0 alpha12. and re-run my project, Xcode gives me an error 'boost/config/user.hpp' file not found, I use brew install boost to install boost. but it doest work. It seems like something wrong with react-native, because I can use Xcode to create a new iOS project and works fine, but when I use 'react-native init newProject', It gives me the same error.

Answer 1

Just remove the cache and the third_party folder in react-native in node modules

 rm -r ~/.rncache
 rm -r <your-project>/node_modules/react-native/third_party

Answer 2

For those who are using react-native version > 0.57

rm -r ~/Library/Caches/com.facebook.ReactNativeBuild
rm -r <your-project>/node_modules/react-native/third_party

Answer 3

I just run the command : npm install and fixed the issue..

Answer 4

for me it was key to remove the ios/Podfile.lock file after removing the ios/Pods/ folder
