I'm creating a custom Angular 7 library, with some directives, pipes and providers common in all projects of the company; however, I'm facing this strange problem when using the module I created, in another project:

h2r-shared-base.js?9483:1023 Uncaught TypeError: Cannot read property 'Directive' of undefined

./node_modules/@h2r/shared-base/fesm5/h2r-shared-base.js

1023:16-20 "export 'default' (imported as 'core') was not found in '@angular/core'

here is angular.json of the lib project:

{

 "$schema": "./node_modules/@angular/cli/lib/config/schema.json",

 "version": 1,

 "newProjectRoot": "projects",

 "projects": {

           "karmaConfig": "projects/shared-base/test/karma.conf.js"

         }

       },

           ],

           "exclude": [

             "**/node_modules/**"

           ]

         }

       }

     }

   }

 },

 "defaultProject": "shared-modules"

}

I don't know why, it appears that it can't find @angular/core. Could someone explain me what could be causing this problem?
