I have only 3 months experience in angular, I tried downgrading the versions but it still gave error also tried to google the solution but didnt find the right solution, would appreciate any help, Thank you.

Solution

Looks like it’s a problem with Peer Dependencies try with npm install –legacy-peer-deps.
