Magento2 为什么我在magento 2中的编译时出错

执行

setup:di:compile

命令时出现此错误

$ php bin/magento s:d:c
PHP Fatal error:  Uncaught Error: Cannot instantiate interface Symfony\Component\Console\Output\OutputInterface in vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php:116

我想问题是由于任何自定义模块di.xml文件造成的，如果您的接口仍然无法加载，请检查您的di.xml并验证首选项是否可用。 我希望你能理解我想向你解释的内容 有关详细信息，请查看下面的链接抽象实现映射主题
