我在Mac OS 10.9.2上运行Rails v4.0.2，我把一切顺利。突然之间，当我尝试rails server时，我发现一个错误，说宝石丢失了。我运行bundle install，这是输出：

我很困惑为什么这个错误突然出现了。几个星期以来，我一直没有问题。我尝试用rvm创建一个新的gemset，但仍然遇到同样的问题。在搜索之后，我找到了首先更新依赖项的建议，然后尝试bundle install，但这并没有解决问题。

遗憾的是，调试器不支持Ruby 2.1.2。相反，请使用byebug gem。 See this discussion了解更多详情。

答案 1 :(得分：24)

调试器 gem不支持Ruby 2.x，您应该使用byebug代替。一旦Rails 4.2.0发布（或者如果你使用Rails 4.2.0rc版本）， byebug 将是Gemfile中包含的默认调试器，但是如果您使用的是早期版本的Rails然后你需要在你的Gemfile中手动进行更改。

只需替换

gem "debugger"

与

gem "byebug"
在您的Gemfile中

并运行bundle install。

更多背景

即使是调试器 gem的维护者也提出了这个建议。 GitHub上的调试器 gem的自述文件具有以下note：

  
      
  • 仅支持1.9.2和1.9.3。对于2.X红宝石，请考虑使用byebug。
    •   

维护者无意修复此问题;他解决了问题debugger can't be installed on ruby 2.X不固定，解释说调试器从未正确支持Ruby 2.X，他现在推荐 byebug 。

此外，调试器的维护者自2014年6月以来没有推送提交甚至回复拉取请求。此时宝石似乎是放弃软件。

Rails本身已采用 byebug 作为{2.}}的Ruby 2.X的官方调试器，从Rails 4.2.0开始，运行rails new my_new_app_name时创建的Gemfile对于Ruby 2.X用户，将引用byebug而不是debugger。

TL;博士

调试器已经死了。使用 byebug 。

答案 2 :(得分：13)

这个命令的怪异最终为我做了诀窍：

gem install debugger-ruby_core_source && ARCHFLAGS="-I$(dirname -- "$(gem which debugger/ruby_core_source/ruby-$(ruby -v | awk '{sub(/p/, "-p", $2); print $2}')/vm_core.h)") -include vm_core.h" bundle install

道歉。

打破它：

  • 首先，安装Ruby标头。

    gem install debugger-ruby_core_source

  • 现在，如果成功，我们想运行bundle install，但它需要能够找到那些Ruby标头。打算gem contents debugger-rebuy_core_source的输出，我们发现它为Ruby的不同补丁级别安装了一堆不同的标题：

    $ gem contents debugger-ruby_core_source | grep vm_core.h
/Users/andrew/.gem/ruby/2.0.0/gems/debugger-ruby_core_source-1.3.2/lib/debugger/ruby_core_source/ruby-1.9.2-p290/vm_core.h
/Users/andrew/.gem/ruby/2.0.0/gems/debugger-ruby_core_source-1.3.2/lib/debugger/ruby_core_source/ruby-1.9.2-p318/vm_core.h
/Users/andrew/.gem/ruby/2.0.0/gems/debugger-ruby_core_source-1.3.2/lib/debugger/ruby_core_source/ruby-1.9.2-p320/vm_core.h
...

  • 目前的补丁级别是什么？

    $ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]

    要将其转换为ruby-2.0.0-p318 gem使用的debugger-ruby_core_source格式，我们使用awk仅打印该版本字符串的第二个字段，并更改p到-p：

    $ ruby -v | awk '{sub(/p/, "-p", $2); print $2}'
2.0.0-p481

  • 现在我们运行bundle install，ARCHFLAGS设置为将包含ruby标头的目录添加到包含文件搜索路径，并预加载vm_core.h：

    gem install debugger-ruby_core_source \
  && ARCHFLAGS="-I$(dirname -- \
    "$(gem which debugger/ruby_core_source/ruby-$(ruby -v | awk '{sub(/p/, "-p", $2); print $2}')/vm_core.h)") \
    -include vm_core.h" \
bundle install

    即，

    gem install debugger-ruby_core_source \
  && ARCHFLAGS="-I<path-to-dir_containing_vm_core.h> -include vm_core.h" \
    bundle install

答案 3 :(得分：5)

对于使用gem 'pry-debugger'的用户，只需将其更改为gem 'pry-byebug'中的Gemfile。

答案 4 :(得分：4)

不幸的是没有答案解决了这个问题。正如nickh之前所回答的，“调试器不支持Ruby 2.1.2。”

我发现了一个允许我安装此宝石的日文帖子，但我不承担任何责任，因为它不是正式版本。这样做需要您自担风险：

git clone https://github.com/mekishizufu/debugger.git
cd debugger
git checkout ca451a9bdf
gem build debugger.gemspec
gem install debugger-1.6.6.gem
