Execution of ng build --prod --aot (npm run-script build-prod) for Angular 4 failed:

ERROR in Unexpected value 'Gravatar in c:/myapp/node_modules/@infinitycube/gravatar/src/gravatar.js' declared by the module 'AppModule in c:/myapp/src/app/app.module.ts'. Please add a @Pipe/@Directive/@component annotation.

Without --aot (dev mode) application works.
