ruby-1.9.3-preview1 上的 ruby​​-debug19 [重复]

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”

我在调试 ruby​​ 1.9.3 preview1 版本时遇到了一些问题。

我已经使用 rvm 安装了 1.9.3 和以下命令：

rvm install 1.9.3 --reconfigure --debug -C --enable-pthread

并用这个安装了 ruby​​-debug19：

gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-preview1

调试 gem 安装良好，但是当我打开带有调试功能的控制台或尝试任何带有调试标志 rails c --debug 或 rspec spec --debug 的东西时。我收到以下错误：

Answer 1

这是rafaeldx7 的alternate solution I found in a Gist。

基本上，解决方案是使用几个库的较新版本，linecache19 v0.5.13 和 ruby-debug-base19 v0.11.26，这两个库都没有包含在 RubyGem 存储库中。

# Install with:
# bash < <(curl -L https://raw.github.com/gist/1333785)
#
# Reference: http://blog.wyeworks.com/2011/11/1/ruby-1-9-3-and-ruby-debug

echo "Installing ruby-debug with ruby-1.9.3-p0 ..."

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

gem install linecache19-0.5.13.gem ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p0/

rm linecache19-0.5.13.gem ruby-debug-base19-0.11.26.gem

echo "Done."

Answer 2

编辑： git-pinning 解决方案起初有效，但我无法始终如一地使用它。我将把它留在这里，因为人们对它投了赞成票，但我认为我的 ruby​​-debug CLI 是偶然的，因为它是以非常规的方式打包的。

我建议改用pry；它似乎是 ruby​​-debug 等等。另外，我也使用require 'debug' 有一段时间了，在答案的顶部提到（可能还有人们赞成的内容），它让你进入的范围通常不是你所期望的。再次使用 pry（请注意，如果您想要类似调试器的步进，您还需要 this pry plugin，我还没有需要/测试过）。

看到Rails with ruby-debugger throw 'Symbol not found: _ruby_current_thread (LoadError)'（总结：你现在可以使用1.9s内置的调试器）就在我想通了以下之后：

由于我注意到您正在尝试让它与 Rails 一起使用，如果您使用的是 bundler，您可以将其添加到您的 gemfile：

gem 'linecache19', :git => 'https://github.com/mark-moseley/linecache.git' 
gem 'ruby-debug-base19', :git => 'https://github.com/mark-moseley/ruby-debug.git'

然后执行：

bundle config build.ruby-debug-base19 --with-ruby-include="$rvm_path/src/$(rvm tools strings)/"
bundle install

Answer 3

我创建了一个 Rubygems 存储库，其中包含 1.9.3 的最新版本。

只需在您的 Gemfile 中添加此源代码行，一切就绪：

source 'http://rubydebug19.s3.amazonaws.com'

gem 'ruby-debug19', :group => :development

这是一个临时解决方案：http://blog.wyeworks.com/2011/11/1/ruby-1-9-3-and-ruby-debug

网站摘录：

首先下载linecache19-0.5.13.gem和 ruby-debug-base19-0.11.26.gem 来自 http://rubyforge.org/frs/?group_id=8883，然后……

$ 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=/Users/santiago/.rbenv/source/ruby-1.9.3-p0  
Building native extensions.  This could take a while...
Successfully installed ruby-debug-base19-0.11.26
1 gem installed
$ irb
irb(main):001:0> require 'ruby-debug'

Answer 5

这是我为使用 Bundler 1.x 和 Ruby 1.9.3-p0（已发布的稳定版本）所做的工作。希望这很快就会过时，但与此同时，如果您需要，这是一个可行的解决方法。

首先，将 linecache 和 ruby​​-debug-base gem 安装为系统 gem。请注意，这些是我从不同的地方获得的。

$ curl -OL http://rubyforge.org/frs/download.php/75415/ruby-debug-base19-0.11.26.gem
$ gem install linecache19-0.5.13.gem
$ gem install --pre ruby-debug-base19x # installs ruby-debug-base19x-0.11.30.pre4

接下来，为每个已安装的 gem 重新创建 gem 源代码：

$ mkdir ~/src/linecache19
$ cd /r193 # where your 1.9.3 is installed; system dependent
$ cd lib/ruby/gems/1.9.1 # where your gems are, should be the same
$ cp specifications/linecache19.gemspec ~src/linecache19
$ cp -r gems/linecache19-0.5.13/* ~/src/linecache19

$ mkdir ~/src/ruby-debug-base19x
$ cp specifications/ruby-debug-base19x-0.11.30.pre4.gemspec ~/src/ruby-debug-base19x
$ cp -r ruby-debug-base19x-0.11.30.pre4/* ~/src/ruby-debug-base19x

现在您可以使用 :path 指令在您的 Gemfile 中引用这些目录。如果你有一个本地 git 存储库，你可以在那里添加提交这些目录并从你的 Gemfile 中引用它们，如下所示：

group :development do
  gem 'linecache19', '~>0.5.12', :git => 'git://git-repo/ruby/linecache19.git'
  gem 'ruby-debug-base19x', :git => 'git://git-repo/ruby/ruby-debug-base19x.git'
  gem 'ruby-debug19', :require => 'ruby-debug'
  gem 'ruby-prof'
end

自 1.9.3-p125 以来，这些答案中的大多数已经过时了。
