ruby-on-rails - 无法加载这样的文件 -- mysql2/mysql2

Question

我正在 m1 mac 上进行安装，但遇到了 mysql 问题。

我的 rails 服务器工作正常，但是当我运行我的规范时，我得到了 cannot load such file -- mysql2/mysql2 错误

有人可以帮我吗？

rspec 规范/

An error occurred while loading rails_helper.
Failure/Error: require File.expand_path('../../config/environment', __FILE__)
