我正在尝试使用此composer.json使用旧的php projet：

运行php composer.phar install时，它会打印：
Your requirements could not be resolved to an installable set of packages.

我不明白这个错误。我该怎么做才能composer.json工作？
答案 0 :(得分：1)
答案在错误消息中。您需要Symfony版本2.2.4，而doctrine-fixtures-bundle（2.3）需要Symfony 2.3。因此，您必须降低灯具套件版本或提高Symfony版本。目前，您要求的版本无法一起使用。
