我无法安装调试器以在我的 ruby 文件中工作。任何人都可以看到问题是什么？
我在 file.rb 的顶部做了“需要调试器”，运行时出现了这个错误ruby file.rb
rubygems/custom_require.rb:36:in `require': cannot load such file -- debugger (LoadError)
我gem install debugger在我的系统上做了，但收到了这个错误消息。
ERROR: Error installing debugger:
ERROR: Failed to build gem native extension.

necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

当我运行 gem 环境时，我得到
