From composerdocumentation :
从composer文档：
If you have been pointed to this page, you want to check a few things:
如果您已被指向此页面，您需要检查以下几点：
If you are using ESETantivirus, go in "Advanced Settings" and disable "HTTP-scanner" under "web access protection" If you are using IPv6, try disabling it. If that solves your issues, get in touch with your ISPor server host, the problem is not at the Packagistlevel but in the routing rules between you and Packagist (i.e. the internet at large). The best way to get these fixed is raise awareness to the network engineers that have the power to fix it.
如果您使用的是ESET防病毒软件，请进入“高级设置”并禁用“Web 访问保护”下的“HTTP 扫描程序”。如果您使用的是IPv6，请尝试禁用它。如果这解决了您的问题，请联系您的ISP或服务器主机，问题不在于Packagist级别，而在于您和 Packagist 之间的路由规则（即整个互联网）。修复这些问题的最佳方法是提高对有能力修复它的网络工程师的认识。
To disable IPv6on Linux, try using this command which appends a rule preferring IPv4over IPv6to your config:
要在Linux上禁用IPv6，请尝试使用此命令，该命令将优先使用IPv4而非IPv6的规则附加到您的配置中：
sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"
If none of the above helped, please report the error.
如果以上都没有帮助，请报告错误。
