如何在 ruby​​ 1.9.3/Rails 3.2.1 中安装 ruby​​-debug [英] how do I install ruby-debug in ruby 1.9.3 / Rails 3.2.1

问题描述

可能重复:
Rails 3.1 和 Ruby 1.9.3p125:ruby-debug19 仍然崩溃，并出现 “Symbol not found: _ruby_threadptr_data_type”

我已经完成了打印到控制台的工作——我想进入 20 世纪并开始使用调试器！！但是如何安装 ruby​​-debug?当我尝试安装 ruby​​-debug19 gem 时，ruby-debug.c 的本机编译失败.我查看了其他 SO 帖子，但尚未找到答案...

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...

• 我使用的是 Ruby 1.9.3-p0
• 我使用的是 Rails 3.2(当然是 Gemfile)
• 我没有使用 RVM - 相反，我有一个包含所有可执行文件、gem、源等的完全沙盒目录.我在下面将其称为 $SANDBOX...

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，并出现 conflicting types for '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
...
Installing ruby-debug-base19 (0.11.25) with native extensions

从命令行安装 ruby​​-debug 不起作用

如果我尝试从命令行构建 gem，使用指向当前 ruby​​ 的 include 目录的 --with-ruby-include 参数，我会得到同样的错误:

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
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug19:

我错过了什么?

--with-ruby-include 是否期待不同的东西?当前的 ruby​​-debug19 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，我找到了一个可行的方法.

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gem

% gem install linecache19-0.5.13.gem
Building native extensions.  This could take a while...
Successfully installed linecache19-0.5.13
1 gem installed
...
% gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$SANDBOX/packages/ruby-1.9.3-p0
Building native extensions.  This could take a while...

更新您的 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

捆绑安装和测试调试器

% 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"
