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

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)

任何的想法？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"

现在有效.

杰罗姆是正确的,但缺乏细节.这是一个打击,来自这个https://gist.github.com/1331533,特别感谢andrewroth的帖子.截至本文发表时,我已对此进行了测试.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'调试器',这是一个ruby-debug(19)的分支,适用于1.9.2和1.9.3,可以很容易地安装rvm/rbenv rubies.它使错误消失!

Answer 3

看起来这是ruby-debug-base中的一个已知错误.我在bug跟踪器上添加了我对该问题的评论.请考虑添加您的笔记:

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,请访问rubyforge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

调试器现在应该工作.

谢谢杰罗姆
