我有标准的 ruby​​-head 和 Rails 3.1rc4。我按照http://dirk.net/2010/04/17/ruby-debug-with-ruby-19x-and-rails-3-on-rvm/的说明安装了 ruby ​​-debug

但是当我运行rails s --debugger它会抛出这个奇怪的错误

/Users/schovi/.rvm/gems/ruby-head/gems/activesupport-3.1.0.rc4/lib/active_support/dependencies.rb:237:in `require': dlopen(/Users/schovi/.rvm/gems/ruby-head/gems/linecache19-0.5.12/lib/trace_nums19.bundle, 9): Symbol not found: _ruby_current_thread (LoadError)

任何想法？谢谢，大卫

更新：

看起来你只需要把它放在你的 gemfile 中：

宝石“调试器”

现在工作。

杰罗姆是正确的，但缺乏细节。以下是来自https://gist.github.com/1331533的一击一击，特别感谢 andrewroth 的帖子。截至本文发布时，我已经对此进行了测试。人们希望这些更改将很快被部署到某个标准的地方。

Installing ruby debugger on ruby 1.9.3-p125: 

export PATCH_LEVEL=`ruby -e 'puts RUBY_PATCHLEVEL'`
export RVM_SRC=$HOME/.rvm/rubies/ruby-1.9.3-p$PATCH_LEVEL/include/ruby-1.9.1
gem install archive-tar-minitar
gem install ruby_core_source -- --with-ruby-include=/$RVM_SRC
export RVM_SRC=$HOME/.rvm/rubies/ruby-1.9.3-p$PATCH_LEVEL/include/ruby-1.9.1/ruby-1.9.3-p$PATCH_LEVEL

wget http://rubyforge.org/frs/download.php/75415/ruby-debug-base19-0.11.26.gem
wget http://rubyforge.org/frs/download.php/63094/ruby-debug19-0.11.6.gem
wget http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
gem install linecache19-0.5.13.gem -- --with-ruby-include=/$RVM_SRC
# if that step failed, and you are running OSX Lion, then following this post can help you: 
# http://stackoverflow.com/questions/8032824/cant-install-ruby-under-lion-with-rvm-gcc-issues
# this happens if you recently installed xcode from the app store. 
# bizarrely, for me I had to do this: ln -s /usr/bin/gcc /usr/bin/gcc-4.2
gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=/$RVM_SRC

Then edit Gemfile: 

gem 'linecache19', '0.5.13', :path => "~/.rvm/gems/ruby-1.9.3-p#{RUBY_PATCHLEVEL}/gems/linecache19-0.5.13/"
gem 'ruby-debug-base19', '0.11.26', :path => "~/.rvm/gems/ruby-1.9.3-p#{RUBY_PATCHLEVEL}/gems/ruby-debug-base19-0.11.26/"
gem 'ruby-debug19', :require => 'ruby-debug'

Then install: 

bundle install

我使用了gem 'debugger'，它是 ruby​​-debug(19) 的一个分支，适用于 1.9.2 和 1.9.3，并且可以轻松安装 rvm/rbenv rubies。它使错误消失！

目前看来，这是 ruby​​-debug-base 中的一个已知错误。我已将我的评论添加到错误跟踪器上的问题中。请考虑添加您的笔记：

http://rubyforge.org/tracker/index.php?func=detail&aid=29222&group_id=8883&atid=34290

同时，ruby 1.9 有一个内置的调试器；它只是很慢。手动将此 require 行添加到您的代码中：

require 'debug'

此外，默认情况下，调试器会中断所有 StandardError 异常，因此请在首次启动时执行此操作：

catch off

如果您运行的是 Ruby 1.9.3x，要修复它，请转到ruby​​forge 上的 ruby​​-debug ，下载并安装 ruby​​-debug-base 0.11.26 和 linecache19 0.5.13。修改您的 Gemfile 以使用这些文件，然后运行

bundle update ruby-debug-base19

调试器现在应该可以工作了。

谢谢杰罗姆

这是修复升级到所有调试的最新 gem

我的系统是 Mac OSX 10.8.5 上的 rvm 1.18.10 和 ruby​​ 1.9.3p392。我首先安装了 gem 'ruby-debug19'，但由于众所周知的原因，调试器没有工作。

然后我跑了

local$ gem install 'debugger'

正如许多其他帖子所建议的那样。gem 安装成功，输出如下：

local$ gem install debugger
Fetching: debugger-ruby_core_source-1.2.3.gem (100%)
Fetching: debugger-linecache-1.2.0.gem (100%)

local$ irb

然后我跑了

local$ rails server --debug

......

我通过注释掉“gem 'ruby-debug19'”行并在 Gemfile 中添加新行“gem 'debugger'”解决了这个错误，然后运行

local$ bundle update

之后，一切正常。

local$ rails server --debug

使用 ruby​​ 1.9.3，我能够通过添加 gem 'ruby-debug-base19x'（注意名称末尾的'x'）和'ruby-debug19'来使其工作。
