@SohaibKtb it should be also added to babel.config.js: https://docs.swmansion.com/react-native-reanimated/docs/installation#babel-plugin

I just wanna add that I have the same problem with a clean new project aswell:

"react": "16.13.1",
"react-native": "0.63.3",
"react-native-reanimated": "^2.0.0-alpha.8"

Having the same issue

My flow to fix was:

ensuring babel plugin installed and added to babel.config.js
watchman watch-del-all && yarn start --reset-cache

This Error still persists @jakub-gonet please can you take a look at this 🥺

Removing related app folder and ModuleCache from derived data solves this problem. Your flow should probably include that clean step anyway: https://stackoverflow.com/questions/58927291/when-can-i-safely-delete-xcode-deriveddata-folder

the same

mohamed-sultan on Nov 8, 2020

Just making sure: did you remove all caches?

node_modules/ (rm -rf node_modules)
metro cache (react-native start --clear-cache)
watchman cache (watchman watch-del-all)
Gradle cache (gradle clean in android/ folder)
Pods cache (rm -rf Pods/ && pod instal)
Build artifacts from xcodebuild (clean project in xcode)

If none of the above commands fixes your problem please provide a reproduction repo so we can investigate it locally. Closing for now as build or config issue; will reopen when we’ll be able to repro it.

@somebody32 I did it also, see the description I provided in the first post I followed the installation instructions on the documentation page step by step
