React native Unable to resolve module expo-modules-core - Creative Tim Argon UI KIT

Question

I try to install https://www.creative-tim.com/product/argon-pro-react-native, a template from Creative Tim for React Native. I follow all the steps, and when I launch Expo Go, I have this error :

Unable to resolve module expo-modules-core from /Users/MYNAMES/Desktop/argon-pro-react-native-v1.6.0/node_modules/expo-splash-screen/build/SplashScreen.js: expo-modules-core could not be found within the project.

If you are sure the module exists, try these steps:
1. Clear watchman watches: watchman watch-del-all
2. Delete node_modules and run yarn install
3. Reset Metro's cache: yarn start --reset-cache
4. Remove the cache: rm -rf /tmp/metro-*

When I check in node_modules, the file SplashScreen.js exist. But expo-modules-core, I don't know exactly where is it supposed to be ?

Here is my package.json

So I'm block on this error. I already try the 4 step (clear Watchman etc.)

Answer 1

I reached the same error message while going through a React Native course on Udemy and it seems to be related to Expo changing the way it's modules should be installed.

Running this command on my terminal solved it:

expo install expo-modules-core
