プログラミング初学者でLaravel入門(青本)を参考に学習を進めています。
.env や database.php など問題個所と考えられる部分を調べましたが原因がわからなかったため、質問させていただきます。
php artisan migrate を実行すると以下のようなエラーメッセージが出ます。
発生しているエラーメッセージ

migrateの実行までに行ったこと
SQliteのインストール
database.phpのデフォルトの値を'mysql'から'sqlite'に変更
.envのDB_CONNECTIONを'mysql'から'sqlite'に変更、不要な部分をコメントアウト
php artisan make:migration コマンドでファイル作成
テーブル生成の処理(2019_10_22_044406_create_books_table.php)
touch コマンドでデータベースファイル作成
