First run

npm i cordova-ios

and then

ionic cordova run ios --project="social-carpooling-frontend"

, if u have the same error try to remove node_modules and run:

npm i

, also u can try before with:

ionic cordova prepare ios

As the error message itself says "No valid Android SDK root found" can you check your environment variables and setup of the android SDK
