所以一开始它给我的错误是，我的PHP版本(7.0.1)对于symfony 3.3来说太低了，它必须至少=>7.0.8。
所以我卸载了xampp，但将htdocs保存为备份，获得了7.1.10并重试，这时我注意到netbeans中的一个laravel项目和symfony项目开始出现错误。
所以我尝试安装FOS，这个错误现在弹出，更新了我的composer，因为我认为它来自composer的未更新版本，但事实并非如此，因为错误是一样的。
我看到了另一个帖子，但不是同一个问题，所以我想在这里寻求帮助，因为我是新手。
但我明白，如果我有FOS Bundle，我的生活会更轻松，所以我真的希望它能开始。
所以请帮帮我，我该怎么办？附言：我刚刚从桌面上剪切了我的htdocs文件夹，并将其粘贴到xamp-dir中，并替换了元素。

问题是FOSUser 1.3不能与Symfony 3.3一起使用，您必须使用FOSUser 2.0并像一样安装它
composer require friendsofsymfony/user-bundle "~2.0"
这应该能解决你的问题。
