Memcache「存在しないサービス「cache.backend.memcache」エラー

Memcache.soとmemcached.soが正常に実行され、両方がphpinfoに表示されています。正しいphp.iniファイルに設定し、すべてのサービスを再起動しました。

ご覧のとおり、memcacheモジュールを有効にできません。

Memcacheモジュールを有効にする必要があります前にモジュールを構成します。サービスは、モジュールが有効な場合にのみ存在します。

少なくともredisモジュールを使用すると、手動でクラスローダーに登録して、services.ymlファイルを明示的に追加することもできますが、それがmemcacheにも当てはまるかどうかはわかりません。 https://docs.platform.sh/frameworks/drupal8/redis.html を参照してください
