问题背景
brew install php@8.3 时报错：libnghttp3.rb装失败
Error: php@8.3: Failed to download resource "libnghttp3.rb"
Download failed: https://raw.githubusercontent.com/Homebrew/homebrew-core/75a3d673d6077eced34810e4c85fcbdd05caf0b3/Formula/lib/libnghttp3.rb已经通过 mac电脑brew update很慢咋办？此文镜像源换成清华的也不行，
解决方案：
后面通过站长工具：https://ping.chinaz.com/raw.githubusercontent.com 测试出此地址的IP
在/etc/hosts文件解析此域名：185.199.109.133 raw.githubusercontent.com
安装成功
