When I try to run npm install in ReactNative project, I get this error.To solve this I try to install whatwg-fetch@^1.0.0 also but same error .
UNMET PEER DEPENDENCY firstname.lastname@example.org
npm WARN email@example.com requires a peer of whatwg-fetch@^1.0.0 but none was installed.
npm ERR! code 1
you need to manually install missing peer dependencies
npm install whatwg-fetch@^1.0.0 --save
