我已完成打印到控制台 - 我想向上移动到20世纪，并开始使用调试器！但是，我该如何安装ruby-debug？当我尝试安装ruby-debug19 gem时，本地编译的 ruby​​-debug.c 失败。我查看了其他SO帖子，但还没有找到答案...

I'm done with printing to the console -- I want to move up to the 20th century and start using a debugger!! But how do I install ruby-debug? The native compilation of ruby-debug.c fails when I try to install the ruby-debug19 gem. I've looked over other SO postings and haven't found the answer yet...

• 我使用Ruby 1.9.3-p0


• 我使用Rails 3.2（当然是使用Gemfile）


• 我没有使用RVM，而是有一个完整的沙盒目录所有可执行文件，宝石，源代码等。我将它称为$ SANDBOX，下面...

如果我将ruby-debug19添加到我的Gemfile中，并执行 bundle install ，则在使用冲突的类型为'rb_iseq_compile_with_option'：

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':

# file: Gemfile
...
group :development do
  gem 'ruby-debug19'
end
...

% bundle install
...

gem从命令行安装ruby-debug doesn' t work

如果我尝试从命令行创建gem，则使用--with-ruby-include参数指向 include 目录为目前的红宝石，我得到了同样的错误：

gem install ruby-debug from the command line doesn't work

If I try building the gem from the command line, using the --with-ruby-include argument pointing at the include directory for the current ruby, I get the same error:

% gem install ruby-debug19 -- --with-ruby-include=$SANDBOX/packages/ruby-1.9.3-p0

我缺少什么？

是--with-ruby-include期望有什么不同？当前的ruby-debug19被破坏了吗？

what am I missing?

Is --with-ruby-include expecting something different? Is the current ruby-debug19 broken?

推荐答案

感谢@Marc Talbot在OP中的评论，我发现了一个工作配方。

Thanks to @Marc Talbot's comment in the OP, I found a working recipe.

% curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
% curl -OL http://rubyforge.org/frs/download.php/75415/ruby-debug-base19-0.11.26.gem

编译这两个宝石

compile the two gems

% gem install linecache19-0.5.13.gem

Successfully installed linecache19-0.5.13

% gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$SANDBOX/packages/ruby-1.9.3-p0

更新您的Gemfile

update your Gemfile

# file: Gemfile
...
group :development do
  gem 'linecache19', '0.5.13'
  gem 'ruby-debug-base19', '0.11.26'
  gem 'ruby-debug19', :require => 'ruby-debug'
end

安装并测试调试器

bundle install and test the debugger

% bundle install
Fetching source index for http://rubygems.org/
...
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
% irb
irb(main):001:0> require 'ruby-debug'
=> true
irb(main):002:0> debugger
$SANDBOX/usr/lib/ruby/1.9.1/irb/context.rb:166
@last_value = value
(rdb:1) p 'hooray'
"hooray"
