Question

可能重复：
Rails 3.1 and Ruby 1.9.3p125: ruby-debug19 still crashes with “Symbol not found: _ruby_threadptr_data_type”

我已完成打印到控制台 - 我希望升级到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。我查看过其他SO帖子但尚未找到答案...

我使用的是Ruby 1.9.3-p0
我正在使用Rails 3.2（当然还有Gemfile）
我没有使用RVM - 相反，我有一个完整的沙盒目录，其中包含所有可执行文件，宝石，资源等。我在下面将它称为$ SANDBOX ...

捆绑安装不起作用

如果我将ruby-debug19添加到我的Gemfile并执行bundle install，则在使用conflicting types for 'rb_iseq_compile_with_option'构建时失败：

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

% bundle install
...

gem install命令行中的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-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？

是否--with-ruby-包括期待不同的东西？当前的ruby-debug19是否已损坏？

Answer 1

感谢@Marc Talbot在OP中的评论，我发现了一个工作方法。

从RubyForge下载linecache19和ruby-debug-base19：

% 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

编译两个宝石

% 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...
Successfully installed ruby-debug-base19-0.11.26
1 gem installed
...

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

bundle安装并测试调试器

% 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"

希望这会有所帮助。

Answer 2

（从您的日志中，我假设您使用的是Linux，特别是Debian发行版）有一个简单的解决方案：在shell中，

sudo apt-get install ruby-dev1.9.3

注意：我实际上并不知道是否有名为ruby-dev1.9.3的软件包，因为我为1.9.2安装了ruby-dev，这是ruby-dev1.9（我认为。那是一个如果有人知道它们是什么，请发表评论。

此软件包安装解释器所需的C扩展所需的标头（ruby.h）。

如何在ruby 1.9.3 / Rails 3.2.1中安装ruby-debug
