我对这个 rails 框架工作和通过在线教程学习完全是新手。我正在 rails(rails+Mysql).
的帮助下开发一个简单的应用程序
目前我遇到了 "rake" 命令的问题。
当我尝试 "rake db:schema:dump" 时出现以下错误 coming.Pls 给我一些建议。
提前致谢。

调试器 gem 似乎遇到了一些问题，但不确定是什么问题
发现问题:: "debugger" gem 与 ruby 2.x 版本不兼容。
因此在 gem 文件和 运行 "rbenv rehash" "bundle install" 中注释了调试器...所有问题都已解决。

调试器 gem 似乎遇到了一些问题，但不确定是什么问题
发现问题:: "debugger" gem 与 ruby 2.x 版本不兼容。
