解决方案：

一脸懵逼的我看到有一个关键字ActiveSupport,然后就搜了搜是个啥东西？

ActiveSupport 是 Ruby on Rails 框架中的一个核心库，旨在扩展和增强 Ruby 语言的功能。它提供了大量实用工具和扩展，使得日常的 Ruby 编程更加方便和高效。这些工具涵盖了诸如日期处理、字符串操作、数值计算等多个方面，并且引入了许多有助于简化代码编写和维护的对象和方法。

想着应该是这个版本出啥问题了，所以就搜了个命令重新安装了下好了。具体步骤如下：

• '把老版本卸载下activesupport'

sudo gem uninstall activesupport

下载最新版本ActiveSupport

• 执行命令 sudo gem install activesupport

• 看下安装的情况 gem list。

• 验证是否成功

  pod --vresion

好了问题解决了
