作曲家安装或更新错误，是什么问题

问题描述

我有问题。命令后

composer update

我收到错误信息

 [Symfony\Component\Console\Exception\LogicException]
  An option named "connection" already exists.


Script Sensio\Bundle\distributionBundle\Composer\ScriptHandler::clearCache handling the symfony-scripts event terminated with an exception


  [RuntimeException]
  An error occurred when executing the ""cache:clear --no-warmup"" command:





    [Symfony\Component\Console\Exception\LogicException]
    An option named "connection" already exists.

我做错了什么？

我使用 git 获取所有项目，并且在一台计算机上全部运行，第二台未运行。

解决方法

运行带有 -vvv 标志的命令。它会告诉你哪个命令被破坏了。例如：

bin/console -vvv

我在升级 doctrine/dbal 包后遇到同样的错误。在我的情况下，RunSqlDoctrineCommand（来自 doctrine/doctrine-bundle 包）与父 RunSqlCommand（来自 doctrine/dbal 包）冲突。我已经更新了 doctrine/doctrine-bundle:1.12.*，它包含针对这种情况的修复。这解决了这样的问题。

就我而言，symfony v3.3 的某个项目在 composer install 下执行 PHP 7.4 失败，并且 PHP 7.2 说 An option named "connection" already exists.。

经过测试的解决方案：

降级到PHP 7.0，它与SF完美配合v3.3
将 symfony 升级到 v3.4，它与 PHP 7.2 和 7.4 完美配合。

就我而言

composer update doctrine/doctrine-bundle

谢谢 IStranger
