CakePHP 3.X を入れてみた

CakePHPインストール

その前phpのバージョンCHECK ‘’‘ php -v ’‘’ macOS / Linuxの場合 Composerを使ってインストール Composerがない場合Composerインストールしてね。

# vim composer.json
}
"require": {
    "cakephp/cakephp": "3.4.*"
}

#composer update

エラーが起きました涙！！

cakephp3以後php-intlが必要になるっぽい。下記の記事「CakePHP3を泣きながらインストールした記録 - やったこと」を参考してphp-intlをインストールし、下記の一行を追加

# vim /etc/php.ini
追加
extensions=intl.so

もう一度 composer update

—————–別の方法(もっと簡単な方法)————————-

Cakephpプロジェクトを作成

$ php /usr/local/bin/composer self-update && composer create-project --prefer-dist cakephp/app your_app_name
