HerokuにLaravelを配備する "Connector.php 55行目（sqlite）のPDOException

Question

私は最初のLaravelプロジェクトをHerokuに配備しようとしました。これは小さなプロジェクトなので、SQLiteをデータベースとして使用しています。 git push heroku masterを使用してプロジェクトを展開し、インデックスを表示するには、データベースからデータを取得するのリンクをクリックした後、私は次のエラーを取得しています：

PDOException in Connector.php line 55: could not find driver

誰もが、私はこの問題を解決することができるかもしれ方法を知っています？事前に多くの感謝！ :)

Answer 1

SqliteはHerokuの共有拡張機能としてセットアップされていますが、composer.jsonで有効にする必要があります。

{ 
    "require": { 
     "sqlite3": "*" 
    } 
} 

をごcomposer.jsonファイルに：

を追加してみてください。

Answer 2

また、これはHerokuで発生しました。

私が追加：

{ 
    "require": { 
     "ext-pdo_sqlite": "*" 
    } 
}
