“軟件包“ doctrine.common”已被注冊為“ Doctrine.Common”

Question

在全新的流安裝中，即復制我的現有站點並成功啟動“ composer安裝”后，當我執行“ flow”命令時，出現以下錯誤：

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

我真的不知道該怎么辦或導致此問題的原因。 在網絡上也找不到任何內容。

Answer 1

我必須刪除PackageStates.php文件，然后一切正常。

Answer 2

我最近也有這個問題（同事也有）。 刪除Packages/Libraries/doctrine/common並運行composer install可解決此問題。
