sh：symfony-cmd：找不到命令

【中文标题】sh：symfony-cmd：找不到命令

【英文标题】：sh: symfony-cmd: command not found

【发布时间】：2021-10-28 13:25:14

【问题描述】：

我已将 Symfony 5.2 应用程序模板降级为使用 Symfony 4.4，以便允许使用一些需要旧版本 Symfony 的库。问题是当我执行composer install 时，在安装快要结束时出现此错误：

sh: symfony-cmd: 找不到命令

似乎安装大部分都成功了，因为我的vendor 文件夹已创建并填充。但我担心这个错误。

这个错误是什么意思？我该如何解决？

【参考方案1】：

symfony-cmd 是 Symfony Flex 的一部分。您的 composer.json 不包含任何对 Flex 的要求，因此运行 composer require symfony/flex 可能会解决该问题。

【讨论】：

虽然我遇到了composer require 的一些递归问题，但将这个要求添加到composer.json 文件就足以解决问题。谢谢！
