Question

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/

中的说明安装了ruby-debug

但是当我运行rails s --debugger时，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)

from /Users/schovi/.rvm/gems/ruby-head/gems/activesupport-3.1.0.rc4/lib/active_support/dependencies.rb:223:in `block in load_dependency'

有什么想法吗？谢谢，大卫

更新：

看起来你只需要把它放在你的gemfile中：

gem＆＃34;调试器＆＃34;

现在有效。

杰罗姆是对的，但缺乏细节。这是从https://gist.github.com/1331533获得的打击，特别感谢andrewroth的帖子。截至本文发表时，我已经对此进行了测试。人们希望这些变化很快会在标准的某个地方部署。

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'，这是一个ruby-debug（19）的分支，适用于1.9.2和1.9.3，可以轻松安装rvm / rbenv rubies。它使错误消失！

Answer 3

目前看来这是ruby-debug-base中的已知错误。我在bug跟踪器上添加了我对该问题的评论。 Plase也考虑添加你的笔记：

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

与此同时，ruby 1.9有一个内置的调试器;它只是非常慢。手动将此需求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，因此首次启动时会执行此操作：

catch off

Answer 4

如果您正在运行Ruby 1.9.3x，要修复它，请转到ruby-debug on rubyforge，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

调试器应该可以正常工作。

Answer 5

这已修复升级到所有调试的最新宝石

Answer 6

使用ruby 1.9.3，除了'ruby-debug19'之外，我还可以通过添加gem'ruby-debug-base19x'（注意名称末尾的'x'）来实现这一点。

Answer 7

在Mac OSX 10.8.5上，我的系统是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，调试器无法正常工作。

然后我跑了

local$ gem install 'debugger'

正如许多其他帖子所建议的那样。 gem已成功安装，具有以下输出：

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
/usr/local/rvm/gems/ruby-1.9.3-p392/gems/activesupport-3.2.11/lib/active_support/dependencies.rb:251:
in`require': dlopen(/usr/local/rvm/gems/ruby-1.9.3-p392/gems/ruby-debug-base19-0.11.25/lib/ruby_debug.bundle,
9): Symbol not found: _ruby_current_thread (LoadError)

......

我通过注释掉“gem'ruby-debug19'”并在Gemfile中添加一行新的“gem”调试器'来解决这个错误，然后运行

local$ bundle update

之后，一切正常。

local$ rails server --debug
=> Booting WEBrick
=> Rails 3.2.14 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

使用ruby-debugger抛出的Rails'找不到符号：_ruby_current_thread（LoadError）'
