我搜索了几个网站，stackoverflow中的几个主题尝试了几种方法来解决

1. 重新安装了作曲家
2. 重新安装了xampp
3. 将 IPv6 更改为 IPv4 -> 暂时解决了
4. 在另一台电脑上尝试过 -> 同一网络
5. 我把我的 github 令牌保存在composer.json 中，然后又出现了一个错误
6. 按照建议使用 V PN
7. 我在 github 中克隆了 laravel，但是当我需要更新其作曲家“autoload”时，我仍然在随机主题上遇到相同的错误，有时是 laravel/symfony 等。
8. 我尝试根据 Fileinfo 在 Xampp v3.2.1 中无法工作来更改 php.ini [重复]：首先没有“;extension=php_fileinfo.dll”，而是我发现 extension=fileinfo 本身没有被注释
9. 为了超时，我将extendion_max从120更改为360 //我的内存是16
10. 我在一个在线 php 训练营中，没有人有同样的错误，当我寻求帮助时没有人能帮助我

我准备提供更多信息，也许我以错误的方式尝试了一个好方法 欣赏。

新尝试：

按照先生的建议NicoHaase 我回顾了 IPv6 部分 结果如下：

Downloading laravel/laravel (v9.3.8)

（我可以对我所做的每一步进行截图）

所有限制都解决了我的问题 但我认为丢失的答案与代理有关 (31/10/2022)
