    - Installation request for nikic/php-parser (locked at v3.1.1) -> satisfiable by nikic/php-parser[v3.1.1].


Installation failed, reverting ./composer.json to its original content.

解決手順としては、
1.http://phpdoc.org/phpDocumentor.phar
  ここからphpDocumentor.pharを取得
2.上記をvendor/binに配置する

以上です。

使い方

php vendor/bin/phpDocumentor.phar -d 生成したいファイルがあるディレクトリ
上の例ではディレクディレクトリを指定していますが、ファイル単体でいい時は、-dオプションでなくて-fオプションにして、ファイルパスを指定します。

使い方が普通に入れた場合と異なるので気をつけていただければなと。
