Unable to link libraries in React Native

I can not link the libraries of my rea-native project. I try every way in google but it does not help. When I try to open the signature-config.json file in Atom, it says "EPERM: unauthorized operation"

native reagent link

EPERM error: unauthorized operation, scandir & E; //android/app/build/intermediates/signing_config/debug/out/signing-config.json&#39 ;. Run CLI with the –verbose flag for more details.
