bundle install doesn't work
捆绑安装不起作用
If I add ruby-debug19 to my Gemfile and do bundle install, it fails during build with conflicting types for 'rb_iseq_compile_with_option':
如果我将 ruby-debug19 添加到我的 Gemfile 并执行bundle install，它会在构建过程中失败conflicting types for 'rb_iseq_compile_with_option'：

what am I missing?
我错过了什么？
Is --with-ruby-include expecting something different? Is the current ruby-debug19 broken?
--with-ruby-include 期待不同的东西吗？当前的 ruby-debug19 是否已损坏？

（根据您的日志，我假设您使用的是 Linux，特别是 Debian 发行版）对此有一个简单的解决方案：在 shell 中，
sudo apt-get install ruby-dev1.9.3
Note: I don't actually know if there is a package called ruby-dev1.9.3, because I installed ruby-devfor 1.9.2, which was ruby-dev1.9(I think. That was a while ago. If anyone knows what they are, please comment).
注意：我实际上不知道是否有一个名为 的包ruby-dev1.9.3，因为我是ruby-dev为 1.9.2安装的，它是ruby-dev1.9（我认为。那是前一段时间。如果有人知道它们是什么，请发表评论）。
This package installs the headers that the C extensions to the interpreter need (ruby.h).
此包安装解释器的 C 扩展所需的头文件 ( ruby.h)。
