mac os ruby安装升级, cocoapods 安装

一、ruby

先检查ruby 环境

macos 系统里是自带ruby的。只不过版本过低。

ruby -v

1. 通过 Homebrew 安装新版 Ruby

bash

brew install ruby

2. 配置 Ruby 环境变量

对于 Apple Silicon Mac（M1/M2/M3）：

bash

echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc
echo 'export LDFLAGS="-L/opt/homebrew/opt/ruby/lib"' >> ~/.zshrc
echo 'export CPPFLAGS="-I/opt/homebrew/opt/ruby/include"' >> ~/.zshrc
echo 'export PKG_CONFIG_PATH="/opt/homebrew/opt/ruby/lib/pkgconfig"' >> ~/.zshrc

对于 Intel Mac：

bash

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc
echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.zshrc
echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.zshrc
echo 'export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"' >> ~/.zshrc

3. 使配置生效

bash

source ~/.zshrc

4. 验证 Ruby 版本

bash

ruby -v
# 应该显示 3.x 版本，例如：ruby 3.2.2

二 、cocoapods

官网

cocoapods.org/

官网安装

sudo gem install cocoapods
