I work on an App in React-Native / Expo and I can't install firebase.
C:UsersNils est>npm install --save firebase
node-pre-gyp install --fallback-to-build --library=static_library
node-pre-gyp WARN Using request for node-pre-gyp https download

I don't understand why it doesn't work, I don't even know where the problem is comming from ...
For users creating new project with expo-cli or XDE, you will get red screen "Can’t Find Variable Self" after your first "yarn" or "npm install". This is because of new "whatwg-fetch" 3.0.0 published yesterday (https://www.npmjs.com/package/whatwg-fetch 23).So you just need to force dependency to previous version:"whatwg-fetch": "^2.0.4"
It means put it in package.json as "dependency". Manually, with "yarn add whatwg-fetch@2.0.4." Or with "npm add whatwg-fetch@2.0.4".
Everything should now work like a charm.
Hope this helps ;p
