Answer 1

try

Open Terminal, go to your project's root folder and do: cd node_modules/react-native/third-party/glog-0.3.4/ 

Run configure script:. / configure Open Xcode and try to run the application.

Answer 2

I ran into the same problem and fixed these commands: -

yarn

 rm -rf node_modules/ yarn clean cache yarn install 

NPM

 rm -rf node_modules/ npm cache clean npm i 

Answer 3

For me:

 # rm -rf node_modules # npm cache verify (Because I'm using npm version 5.0.3) # npm install Xcode Clean Xcode Run 

If that doesn't work,

In terminal, go to react-native/third-party/glog folder inside node_modules

(for me it was cd node_modules/react-native/third-party/glog-0.3.4 )

Once active in this folder,

 #run ../../scripts/ios-configure-glog.sh 

Glog is configured and the required config.h header file is created for Xcode to find

Answer 4

Just go to the config.h file, click on the right panel and add the file to the application, checking the correct case. Clean and compile again.
