I am suddenly getting this error while creating the new project in expo, when I create any project it loads perfectly and can see the default screen.
When I try to install any dependancy e.g. yarn add native-base it stops working and giving me can't Find Variable Self and Expo gets hanged
Please help thanks in advance
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 email@example.com.” Or with “npm add firstname.lastname@example.org”.
Everything should now work like a charm.
Hope this helps ;p
