我已经将Symfony 5.2应用模板降级为使用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，我在安装结束时得到这个错误:
sh: symfony-cmd: command not found
看起来安装大部分是成功的，因为我的vendor文件夹被创建并填充。但是我很担心这个错误。
这个错误是什么意思?我怎么修理它?

对于那些已经安装了symfony/flex包并且仍然得到错误的人，请确保在运行composer时允许symfony/flex包执行代码。
这是因为自Composer 2.2.0以来，allow-plugins选项增加了一层安全性，允许您限制哪些Composer插件可以在启动时执行代码。
所以确保你在composer.json文件的allow-plugins配置中有合适的行
"config": {
// other config...
"allow-plugins": {
"symfony/flex": true
}
},
symfony-cmd是Symfony Flex的一部分。您的composer.json不包含Flex的任何要求，所以运行composer require symfony/flex可能会解决这个问题。
虽然在项目中添加symfony/flex是一种解决方案，但请记住flex是可选的。如果你想在不安装Flex的情况下消除错误，只需从composer.json中删除symfony-cmd命令引用。
:
"scripts": {
"auto-scripts": {
"cache:clear": "symfony-cmd",
"assets:install %PUBLIC_DIR%": "symfony-cmd"
},
"post-install-cmd": [
"@auto-scripts"
],
"post-update-cmd": [
"@auto-scripts"
]
},
:后
"scripts": {
"auto-scripts": {},
"post-install-cmd": [],
"post-update-cmd": []
},
我遇到了一个特殊的情况，一个旧的部署脚本添加了--no-plugins到我的composer命令。删除它解决了我使用部署器v6的问题。
set('composer_options', '{{composer_action}} --verbose --prefer-dist --no-progress --no-interaction --no-dev --optimize-autoloader');
显然你需要插件flex的工作，我假设，因为脚本块有一些命令，你也需要。所以没有脚本/插件会破坏你的安装。
