Angular+ngx-fomantic-uiで「Error: export ‘ReflectiveInjector’ (imported as ‘ReflectiveInjector’) was not found in ‘@angular/core’」

今回はAngular+ngx-fomantic-uiの環境で下記のエラーが起きる原因についてお話ししていきます。

Angularのバージョンは16.2.14で、ngx-fomantic-uiのバージョンは0.11.7です。

Angular+ngx-fomantic-uiで「Error: export 'ReflectiveInjector’ (imported as 'ReflectiveInjector’) was not found in '@angular/core’」

結論から言うと、ngx-fomantic-uiのライブラリはAngularのバージョン16では動かなく、Angularのバージョン16ではReflectiveInjectorが廃止になっているような動きをし、サーバー起動時にエラーが起きるからです。(下記のリンク先はng2-semantic-uiについてですが、ngx-fomantic-uiも同様の動きと思われます)
https://github.com/edcarroll/ng2-semantic-ui/issues/454

fomantic-uiをAngularで引き続き使い続きたい場合は、2024年6月現在、Angularのバージョンを15以下にするか他のライブラリを使うかしかなさそうです。
