composer installでエラーが発生する

composer installが失敗します。

$ cat composer.json
{
    "require-dev": {
        "phpmd/phpmd": "*",
        "squizlabs/php_codesniffer": "2.*"
    }
}
$ composer install

  [ErrorException]
  zlib_decode(): data error

エラー文言について検索したところ
http://7me.oji.0j0.jp/memo/composer-macosx.html

$ composer config repositories.packagist composer http://packagist.jp
$ composer clear-cache

でエラーがなくなったと書いてあったのですが試してもダメでした。
原因や対応方法など何かご存知の方ご教示をお願いします。

CentOS 7.2.1511 の minimal の環境で検証しましたが再現しないようです。
compsoer install -vvv の内容と実行環境の詳細はどうなっているでしょうか。

bash
1yum install php

3mv composer.phar /usr/local/bin/composer
4composer config -g repos.packagist composer https://packagist.jp

キャッシュをクリアするか、repositories を指定することで解決するケースがあるようですが、いかがでしょうか。

repositoriesを指定するとできました！ありがとうございます！正直なぜできるようになったのかわかりません。もしわかるようでしたら、何でわかったかなど教えて頂けましたら幸いです。

https://github.com/composer/composer/issues/5814 同様のエラーで VirtualBox 5.1.8 だと問題が起きるという斜め上な話があがってますね。ダウングレードかテストビルドで解決したという人がいるようですので、VirtualBox を利用していて、キャッシュクリアや repositories の指定で解決しない場合は VirtualBox のバージョンを変更してみてはいかがでしょうか。 https://www.virtualbox.org/wiki/Testbuilds

あ、すみません、解決したみたいですね。よかったです。解決方法の調べ方ですが、同様にエラーメッセージで検索しています。検索時に "zlib_decode(): data error" とダブルクォーテーションで括ると検索結果の精度が上がるかもしれません。また入れ違いでコメントしてしまいましたが、-vvv でのエラーに記載のある RemoteFilesystem.php で絞り込むと前述のような対策案が見つかります。なお、今回のケースだと英語のサイトをスルーしない前提になります。
