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

作曲家试图告诉我我需要再次安装symfony吗？
这是我的composer.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/ composer / autoload_namespaces.php（是的，我知道这很糟糕）
EDIT2： 当我执行composer.phar update
时# php composer.phar update

感谢您的帮助。
答案 0 :(得分：1)
找到了答案！
虽然看似简单（不适合我），但symfony/class-loader依赖于未引用正确版本的依赖关系。
所以我所要做的就是删除类加载器，一切都很好。
