问题分析 #

从错误路径能明显看出：当前运行的是rbenv管理的Ruby 3.2.2，但加载的date_core.so却是rvm管理的Ruby 2.7.2的gem库文件——这是Ruby版本与gem编译版本不兼容导致的，同时系统里同时存在rvm和rbenv两个版本管理工具，进一步加剧了环境混乱。

解决步骤 #

1. 统一Ruby版本管理工具

   • 选一个工具保留（比如rbenv），卸载另一个（rvm），彻底避免环境变量冲突。
   • 暂时不想卸载的话，先确保当前会话只激活一个工具：
     • 用rbenv的话：先执行rvm use system切到系统Ruby，再执行rbenv local 3.2.2锁定项目Ruby版本。
     • 用rvm的话：先执行rbenv global system，再执行rvm use 3.2.2切换到目标版本。

2. 重装适配当前Ruby版本的gem
   进入项目目录，执行以下命令清理旧依赖并重装：

   rm -rf vendor/bundle
   gem uninstall date
   bundle install
   

   确保bundle安装的gem都存放在当前Ruby版本的gem目录下，而非其他版本的目录。

3. 验证环境一致性
   执行以下命令确认Ruby和gem路径匹配：

   which ruby
   which gem
   

   两个命令的输出路径必须对应同一个Ruby 3.2.2版本。

4. 重新执行迁移

   bundle exec rake db:migrate
