报错这个

pod --version
/opt/homebrew/Cellar/ruby/3.4.3/lib/ruby/3.4.0/rubygems.rb:269:in 'Gem.find_spec_for_exe': can't find gem cocoapods (>= 0.a) with executable pod (Gem::GemNotFoundException)
    from /opt/homebrew/Cellar/ruby/3.4.3/lib/ruby/3.4.0/rubygems.rb:288:in 'Gem.activate_bin_path'
    from /usr/local/bin/pod:25:in '<main>'pod --version

✅ 修复步骤如下：

输入命令
① 查看当前的 pod 链接情况

which -a pod

/usr/local/bin/pod        # ❌ 旧的（gem）
/opt/homebrew/bin/pod     # ✅ 正确的（brew）

② 删除旧的 pod 链接

sudo rm /usr/local/bin/pod

③ 再次检查 pod --version

pod --version

就会版本输出号了

如果你要彻底确保环境没冲突，也可以执行这个：

hash -r  # 清理 shell 缓存
