问题
Recently upgraded from Angular 6 to Angular 11 using https://update.angular.io. Everything went smooth and Angular runs locally using ng serve but when trying to build a production-build using ng serve --prod it gives just following error:
Error: Expected a pseudo-class or pseudo-element.
When using ng build --prod --verbose=true, it results in lot of logs similar to:
WARNING in Conflict: Multiple assets emit different content to the same filename 3rdpartylicenses.txt
WARNING in Conflict: Multiple assets emit different content to the same filename 3rdpartylicenses.txt
ERROR in Expected a pseudo-class or pseudo-element.
