M2 Mac用Homebrew安装PHP失败：freetds下载提示curl未安装

在M2 Macbook（MacOS Ventura 13.4）上通过Homebrew安装PHP，执行brew install php时出现以下错误：

Error: php: Failed to download resource "freetds"
Download failed: Homebrew-installed `curl` is not installed for: https://www.freetds.org/files/stable/freetds-1.3.18.tar.bz2

按提示执行brew install curl后，再次安装PHP仍报相同错误。重新安装curl时，其依赖openssl@1.1编译失败，日志片段如下：

Do not report this issue to Homebrew/brew or Homebrew/homebrew-core!

执行curl --version显示系统已安装x86_64版本的curl：

curl 7.88.1 (x86_64-apple-darwin22.0) libcurl/7.88.1 (SecureTransport) LibreSSL/3.3.6 zlib/1.2.11 nghttp2/1.51.0
Release-Date: 2023-02-20
Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 pop3s rtsp smb smbs smtp smtps telnet tftp
Features: alt-svc AsynchDNS GSS-API HSTS HTTP2 HTTPS-proxy IPv6 Kerberos Largefile libz MultiSSL NTLM NTLM_WB SPNEGO SSL threadsafe UnixSockets

1. Homebrew curl未被识别：系统自带的是x86_64架构的curl，而M2为arm64架构，Homebrew默认要求使用自身编译的arm64版本curl下载资源，因此会提示"Homebrew-installed curl is not installed"。
2. openssl@1.1编译失败：日志中的Killed:9是系统内存不足触发OOM Killer终止进程导致的；另外openssl@1.1已停止维护，Homebrew在arm64架构上对其支持有限，也会加剧编译失败的概率。

步骤1：释放系统内存 #

• 关闭后台闲置应用，释放运行内存；
• 临时扩容虚拟内存：打开「系统设置」→「通用」→「储存空间」→「信息」→「管理」→「存储」→「虚拟内存」，勾选「启用虚拟内存」并分配至少8GB空间。

步骤2：安装兼容的curl版本 #

执行以下命令安装使用系统TLS库的curl，跳过openssl@1.1依赖：

brew install curl --with-secure-transport

若仍有问题，可临时使用系统curl替代Homebrew版本：

# zsh用户
echo 'export HOMEBREW_FORCE_BREWED_CURL="false"' >> ~/.zshrc
source ~/.zshrc

# bash用户
echo 'export HOMEBREW_FORCE_BREWED_CURL="false"' >> ~/.bash_profile
source ~/.bash_profile

步骤3：重新安装PHP #

完成上述操作后，执行命令重新安装：

brew install php

备选方案：使用预编译二进制包 #

若编译问题持续，直接使用Homebrew预编译的PHP包：

brew install php --force-bottle
