FaIconLibrary not found when using angular-fontawesome and font-awesome 5

Question

I have the following error when trying to use @fortawesome/angular-fontawesome in my angular 7 application:

node_modules/@fortawesome/angular-fontawesome/angular-fontawesome"' has no exported member 'FaIconLibrary

I followed the documentation and initialized the module this way:

import { FontAwesomeModule, FaIconLibrary } from '@fortawesome/angular-fontawesome';
(...)

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    (...)
    FontAwesomeModule,
    (...)
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
  constructor(library: FaIconLibrary) {
    library.add(...icons);
  }
}

Here are the exact version I use:

"@angular/core": "7.2.2",
(...)
"@fortawesome/angular-fontawesome": "^0.3.0",
"@fortawesome/fontawesome-pro": "^5.11.2",
"@fortawesome/fontawesome-svg-core": "1.2.21",
"@fortawesome/free-brands-svg-icons": "5.10.1",
"@fortawesome/free-regular-svg-icons": "5.10.1",
"@fortawesome/free-solid-svg-icons": "5.10.1",

Thanks very much for your help! Thierry

If you see release notes, FaIconLibrary is added from version 0.5.0 that is not compatible with angular 7.2.2. Then you should use old way for adding icons, for e.g:

import { FontAwesomeModule } from '@fortawesome/angular-fontawesome';
import { library } from '@fortawesome/fontawesome-svg-core';
import { faSquare, faCheckSquare } from '@fortawesome/free-solid-svg-icons';
import { faSquare as farSquare, faCheckSquare as farCheckSquare } from '@fortawesome/free-regular-svg-icons';
import { faStackOverflow, faGithub, faMedium } from '@fortawesome/free-brands-svg-icons'; 

...

export class AppModule {
  constructor() {
    library.add(faSquare, faCheckSquare, farSquare, farCheckSquare, faStackOverflow, faGithub, faMedium);
  }
}
