Installation failed, reverting ./composer.json to its original content.

因此，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另存为备份，获得了7.1.10并重试，这时我注意到netbeans中的一个laravel项目开始出现错误，symfony项目也出现了错误

所以我试着安装FOS，这个错误现在弹出，更新了我的composer，因为我认为它来自于未更新版本的composer，但不是很明显，因为错误是相同的

我看到了另一个帖子，但问题不一样，所以我想在这里寻求帮助，因为我对这方面还不熟悉

但我明白，如果我有一个包，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？ 另外，我刚刚从桌面上剪切了我的htdocs文件夹，并将其粘贴到xampp dir中，并替换了元素

这是symfony项目中的my composer.json：

我的php版本：

php -v

问题是FOSUser 1.3不能与Symfony 3.3一起使用，您必须使用FOSUser 2.0并按如下方式安装：

composer require friendsofsymfony/user-bundle "~2.0"

---

这将解决您的问题。

您能分享以下内容吗？我相信它会帮助任何想插话的人准确地理解你所面临的问题：（1）你的

composer.json

文件，（2）在命令行输入

php-v

的输出，以及（3）在命令行输入

echo$PATH

的输出。@CameronHurd我做到了，谢谢你的提示：）是的，它做到了！：）
