It seems there are a package compatibility problem, you should follow this guide to upgrade packages to angular 5 to make compatible versions for packages, I've tried it and it worked well

npm install @angular/animations@^5.0.0 @angular/common@^5.0.0 @angular/compiler@^5.0.0 @angular/compiler-cli@^5.0.0 @angular/core@^5.0.0 @angular/forms@^5.0.0 @angular/http@^5.0.0 @angular/platform-browser@^5.0.0 @angular/platform-browser-dynamic@^5.0.0 @angular/platform-server@^5.0.0 @angular/router@^5.0.0 [email protected] rxjs@^5.5.2
