The error message @angular/core has no export member 00InjectableDeclaration occurs when you try to install Bold Reports® 5.2.27 or greater in an Angular version lower than v12. This is because the Bold Reports® package @boldreports/angular-reporting-components requires Angular v12 or higher to function properly.
If you are getting this error message, you can either upgrade your Angular version to 12 or higher, or you can downgrade the Bold Reports® package to a version lower than 5.1.28.
