Mac OS Ventura下Ruby 2.7.5安装失败（OpenSSL配置错误）

问题背景 #

为适配React Native 0.70，在Mac OS Ventura系统中尝试安装Ruby 2.7.5并指定使用OpenSSL 1.1，执行命令：

CONFIG_PATH=/usr/local/opt/openssl@1.1/lib/pkgconfig rvm reinstall 2.7.5 --with-openssl-lib=/usr/local/opt/openssl@1.1 --with-openssl-include=/usr/local/opt/openssl@1.1

安装失败，日志提示OpenSSL扩展未编译，ext/openssl/mkmf.log中出现t_open未定义、-lnsl/-lsocket库找不到、LIBRESSL_VERSION_NUMBER未定义等错误。

解决步骤 #

• 确认OpenSSL 1.1已安装：
  执行brew list openssl@1.1检查，未安装则运行brew install openssl@1.1。
• 设置完整的环境变量，确保编译工具能正确找到OpenSSL 1.1：

  export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"
  

• 使用简化的RVM命令重新安装Ruby 2.7.5，依赖环境变量自动识别OpenSSL路径：

  rvm reinstall 2.7.5 --with-openssl-dir=/usr/local/opt/openssl@1.1
  

• 若仍报-lnsl/-lsocket错误，添加参数忽略这些非Mac系统默认库：

  rvm reinstall 2.7.5 --with-openssl-dir=/usr/local/opt/openssl@1.1 --with-ldflags="-L/usr/local/opt/openssl@1.1/lib" --with-cppflags="-I/usr/local/opt/openssl@1.1/include" --without-tcl --without-tk
  

• 确保Xcode命令行工具是最新状态：
  执行xcode-select --install安装或更新，再运行sudo xcodebuild -license accept接受许可证。
