'包 "doctrine.common" 已经注册为 "Doctrine.Common"

Question

在全新的流程安装中，即在复制现有站点并成功启动 "composer install" 之后，当我执行 "flow" 命令时，出现以下错误：

PHP Fatal error:  Uncaught exception 'TYPO3\Flow\Package\Exception\InvalidPackag
eStateException' with message 'Package "doctrine.common" is already registered a
s "Doctrine.Common".' in C:\Development\my-cyme\Packages\Framework\TYPO3.Flow\Cl

我真的不知道该怎么做或者是什么导致了这个问题。网上也没查到。

Answer 1

我最近也遇到了这个问题（同事也是）。删除 Packages/Libraries/doctrine/common 和运行一个 composer install 解决了这个问题。

Answer 2

我不得不删除 PackageStates.php 文件，然后一切正常。

'包 "doctrine.common" 已经注册为 "Doctrine.Common"

'Package "doctrine.common" is already registered as "Doctrine.Common"
