[CakePHP]composerでCakeをインストールした時にbakeでエラーが出る問題の修正

メモです。

composerでCakePHPといくつかのプラグインをインストールしたらbake modelの、Test/Fixtureの出力の際にエラーが出てしまいました。

composer.jsonはこんな感じで、

{
	"name": "hoge-app",
	"repositories": [
		{
			"type": "pear",
			"url": "http://pear.cakephp.org"
		}
	],
	"require": {
		"pear-cakephp/cakephp": ">=2.4.4",
		"cakephp/debug_kit": "2.2.*",
		"slywalker/boost_cake": "*",
		"cakedc/utils": "*",
		"cakedc/users": "*",
		"cakedc/search": "*"
	},
	"config": {
		"vendor-dir": "Vendor/"
	}
}

CakePHPのインストール、アプリケーションのbake、/webroot/index.phpのCAKE_CORE_INCLUDE_PATHの修正、Config/bootstrap.phpに

// composerのautoloadを読み込み
require APP . '/Vendor/autoload.php';

// CakePHPのオートローダーをいったん削除し、composerより先に評価されるように先頭に追加する
// https://github.com/composer/composer/commit/c80cb76b9b5082ecc3e5b53b1050f76bb27b127b を参照
spl_autoload_unregister(array('App', 'load'));
spl_autoload_register(array('App', 'load'), true, true);

上記を追加など、composerでCakePHPをインストールする際に必要な手順は満たしています。

bake modelでエラー

bake modelすると以下のようなエラーが出ます。

定義済みのAppModelを定義しようとしてエラーが出ているので、おそらくcomposerのauto_loader絡みのエラーだとは当たりを付けられたのですが、どうするべきかわからなかったのでググりました。

こちらにフックスクリプトを利用した解決方法が掲載されていたため利用させていただきました。

composer.jsonにscriptsを追記

composer.json

{
	"name": "hoge-app",
	"repositories": [
		{
			"type": "pear",
			"url": "http://pear.cakephp.org"
		}
	],
	// ↓このブロックを追加
	"scripts": {
		"post-autoload-dump": [
			"./composer_fix_autoload.sh"
		]
	},
	"require": {
		"pear-cakephp/cakephp": ">=2.4.4",
		"cakephp/debug_kit": "2.2.*",
		"slywalker/boost_cake": "*",
		"cakedc/utils": "*",
		"cakedc/users": "*",
		"cakedc/search": "*"
	},
	"config": {
		"vendor-dir": "Vendor/"
	}
}

composer_fix_autoload.shを追加

composer.jsonと同じディレクトリに以下のファイルを追加します。*1

composer_fix_autoload.sh

#!/bin/bash
mv Vendor/composer/autoload_classmap.php Vendor/composer/autoload_classmap.php.bak
sed '/CakePHP\/Cake\/Test\/Case\/Model\/models\.php/d' Vendor/composer/autoload_classmap.php.ori > Vendor/composer/autoload_classmap.php

autoload_classmap.phpをautoload_classmap.php.oriにコピー

cp /Vendor/composer/autoload_classmap.php /Vendor/composer/autoload_classmap.php.ori

composerのupdate

php composer.phar updateを実行して、composer_fix_autoload.shを通すようにする。

これでbake時にエラーが出なくなりました。

composerのvendor-dirが異なる場合は置き換えてください [↩]
