我是Symfony2和composer.phar安装捆绑包的新手。
每次我想安装新捆绑包时，我都会出错。我不知道是我的composer.json坏了，还是我完整安装的Symfony
。# php composer.phar require friendsofsymfony/comment-bundle
Please provide a version constraint for the friendsofsymfony/comment-bundle requirement: dev-master

作曲家是否试图告诉我我需要再次安装symfony？
这是我的作曲家.json

编辑：由于这些错误，我不得不手动安装捆绑包（例如 FOSFacebookBundle），所以我不得不更新供应商/作曲家/autoload_namespaces.php（是的，我知道这很糟糕）
编辑2：当我执行作曲家.phar 更新时
# php composer.phar update

感谢您的帮助。
找到了答案！
尽管看起来很简单（不适合我），但依赖于没有引用正确版本的symfony/class-loader。
所以我所要做的就是删除类加载器，一切都很好。
