我的问题

使用 Alamofire 需要基于 CocoaPods，但是在尝试安装 CocoaPods 的过程中遇到了很多问题，捣鼓了很久都失败了，最后经群里大佬的点播才安装成功，其实有的时候问题的解决方案很简单，希望这篇博文可以帮到你。

尝试安装

步骤：先安装 homebrew，再更新 Ruby，再安装 cocoapods

注：很多网上博客要求安装 rvm，其实 rvm 并非必须，只是更新 Ruby 的一种方式

这里直接引用大佬的博客，参考如下：

macOS 系统安装 Homebrew
macOS 系统更新 Ruby
macOS 系统重新 CocoaPods

我的问题

一般来说按照上面的流程，基本都可以完成安装。这里说一下我的问题，我的问题是 Ruby 版本过低，安装成功前我的版本是 2.6.3p62，在我将 Ruby 版本更新到 3.0.2_1 后，再执行：sudo gem install -n /usr/local/bin cocoapods 就安装成功啦！

这里主要一个问题是：通过 Homebrew 更新了最新的 Ruby，但是使用的时候不一定是最新的，所以导致安装失败。

（其实在上面引用的大佬的文章中有写配置最新的 Ruby 的环境变量，只是一开始没仔细看）

这里列出两个配置 Ruby 环境变量方法：

方法 1:

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

方法 2：

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile

通过 ruby -v 查看 Ruby 版本是否更新，更新成最新的以后再去尝试安装一下吧…
