即使安装了最新版本，Cocoapods 也没有更新

Question

我尝试使用“sudo gem install cocoapods”更新cocoapods，并表示已安装最新的cocoapods。但是，当我运行“pod --version”时，它仍然显示该版本是我之前的 cocoapods 版本。关于如何更新到最新版本有什么建议吗？

xx@xx-MacBook-Air ios % pod --version

我尝试卸载 cocoapods 并重新安装它，按照此建议并使用以下代码：

xx@xx-MacBook-Air ios % sudo gem uninstall cocoapods
Remove executables:
        pod, sandbox-pod

但即使我卸载了 cocopods，pod --version 仍然显示以前的版本。我尝试重新安装最新版本，但版本仍然显示1.10.1

用于which pod找出它的安装位置。很可能它已经通过了brew，因此您需要执行 abrew upgrade来获取最新版本。一般来说，最好通过相同的方法安装所有 Ruby 工具：直接、通过brew或使用 Ruby 管理器（如 ）rvm。
