「Deprecated: Use of `BaseErrorHandler` and subclasses are deprecated. 」の対処法
428 回閲覧されました
みなさんこんにちは、jonioです。
新しく働く会社ではCakePHPを使うので勉強しようと思ってネットの情報を勉強をしてCakePHPの4.1をインストールしてトップページを表示したら画面上に「Deprecated: Use of `BaseErrorHandler` and subclasses are deprecated. Upgrade to the new `ErrorTrap` and `ExceptionTrap` subsystem. See https://book.cakephp.org/4/en/appendices/4-4-migration-guide.html /Applications/MAMP/htdocs/cakephp/CakeBlog/config/bootstrap.php, line: 130 You can disable all deprecation warnings by setting `Error.errorLevel` to `E_ALL & ~E_USER_DEPRECATED`. Adding `config/bootstrap.php` to `Error.ignoredDeprecationPaths` in your `config/app.php` config will mute deprecations from that file only. in /Applications/MAMP/htdocs/cakephp/CakeBlog/vendor/cakephp/cakephp/src/Core/functions.php on line 318」と表示されました。
私と同じようにCakePHPを勉強していきなりエラーが出てどうしようもなくなった人の為にこの記事を残します。
エラー文のURLを見る
エラー文の「Deprecated: Use of `BaseErrorHandler` and subclasses are deprecated. Upgrade to the new `ErrorTrap` and `ExceptionTrap」は「BaseErrorHandlerとsubclassesを使うのは廃止されました。ErrorTrapとExceptionTrapはアップグレードしましょう」という意味です。
この部分で記述でエラーが出ているのが分かります。
エラー文に「See https://book.cakephp.org/4/en/appendices/4-4-migration-guide.html 」とあるのでURLにアクセスして「BaseErrorHandler」の項目(下記参照)を見ます。
エラー文の続きを読むと「Adding `config/bootstrap.php`」とあるので「上記の赤枠をconfig/bootstrap.phpに記述しなさい」という意味だと思います。
bootstrap.phpの修正
「CakePHPのプロジェクト > config > bootstrap.php」のコードの追加・修正をします、下記に変更します。

これでエラー文がなくなります。
