Gem安装调试器错误

apa*_*des 25 ruby gem ruby-on-rails rvm

我在Mac OS 10.9.2上运行Rails v4.0.2并且我顺利完成了一切.我突然发现一个错误,当我尝试时,宝石丢失了rails server.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关系的建议,然后尝试bundle install但这并没有解决问题.

nic*_*ckh 29

遗憾的是,调试器不支持Ruby 2.1.2.相反,使用byebug gem.有关详细信息,请参阅此讨论.

Mar*_*ery 25

调试器 gem 不支持Ruby 2.x ,您应该使用byebug.一旦Rails 4.2.0发布(或者你使用Rails 4.2.0rc版本),byebug将是Gemfile中包含的默认调试器,但是如果你使用的是早期版本的Rails,那么你需要进行更改在您的Gemfile中手动.

只需更换

gem "debugger"

同

gem "byebug"
Run Code Online (Sandbox Code Playgroud)

在你的Gemfile中运行一个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README有以下注释:

  • 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; 他关闭了问题调试器无法安装在ruby 2.X上不固定,解释调试器从未正确支持Ruby 2.X并且他现在推荐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Ruby 2.X的官方调试器,从4月份的pull请求开始,从Rails 4.2.0开始,运行时创建的Gemfile rails new my_new_app_name将引用byebug而不是debuggerRuby 2.X用户.

TL;博士

调试器已经死了.使用byebug.

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

我很抱歉.

打破它:

  • 首先,安装Ruby头文件.

    gem install debugger-ruby_core_source
    Run Code Online (Sandbox Code Playgroud)

  • 现在,如果成功,我们想要运行,bundle install但它需要能够找到那些Ruby头.在输出中gem contents debugger-rebuy_core_source,我们发现它为不同的Ruby 补丁级别安装了一堆不同的头文件:

    $ 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

  • 目前的补丁级别是多少？

    $ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]
    Run Code Online (Sandbox Code Playgroud)

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

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

  • 现在我们运行bundle install,使用ARCHFLAGSset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

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

对于那些正在使用的人,gem 'pry-debugger'只需将其改为gem 'pry-byebug'你的Gemfile.
