Ruby-on-rails Gem 安装调试器错误

Question

提问by apardes

I am running Rails v4.0.2 on Mac OS 10.9.2 and I had everything smoothly. All of a sudden I'm getting an error saying gems are missing when I try rails server. I run bundle install and this is the output:

I am very confused why this error came up all of a sudden. I have been up and running without issue for weeks. I've tried creating a new gemset with rvm and still encounter the same issue. After searching around I found recommendations to update dependencies first and then try bundle installbut this did not solve the issue.

我很困惑为什么这个错误突然出现。我已经启动并运行了数周没有问题。我试过用 rvm 创建一个新的 gemset，但仍然遇到同样的问题。在四处搜索后，我发现建议先更新依赖项，然后再尝试，bundle install但这并没有解决问题。

Ruby 2.1.2 isn't supported by debugger, unfortunately. Instead, use the byebug gem. See this discussionfor more details.

不幸的是，调试器不支持 Ruby 2.1.2。相反，使用byebug gem。有关更多详细信息，请参阅此讨论。

回答by Mark Amery

Ruby 2.x is not supported by the debuggergem and you should use byebuginstead. Once Rails 4.2.0 is released (or if you use the Rails 4.2.0rc versions) byebugwill be the default debugger included in your Gemfile, but if you're on an earlier version of Rails then you'll need to make the change manually in your Gemfile.

调试器gem不支持 Ruby 2.x ，您应该改用byebug。一旦 Rails 4.2.0 发布（或者如果您使用 Rails 4.2.0rc 版本）byebug将是您 Gemfile 中包含的默认调试器，但如果您使用的是早期版本的 Rails，则需要进行更改手动在您的 Gemfile 中。

Just replace

只需更换

gem "debugger"

with

和

gem "byebug"

in your Gemfile and run a bundle install.

在你的 Gemfile 中运行一个bundle install.

This monstrosity of a command ended up doing the trick for me:

这个命令的怪物最终为我做了伎俩：

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

My apologies.

我很抱歉。

Breaking it down:

分解它：

First, install the Ruby headers.
```
gem install debugger-ruby_core_source
```

Now, if that succeeds we want to run bundle installbut it needs to be able to find those Ruby headers. Grepping the output of gem contents debugger-rebuy_core_source, we find that it installs a bunch of different headers for different patchlevels of Ruby:

$ 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
...

What's the current patch level?
```
$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]
```
To transform that into the ruby-2.0.0-p318format used by the debugger-ruby_core_sourcegem, we use awkto print only the second field of that version string, and change the pto -p:
```
$ ruby -v | awk '{sub(/p/, "-p", ); print }'
2.0.0-p481
```

Now we run bundle install, with ARCHFLAGSset to add the directory containing the ruby headers to the include file search path, and preload 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", ); print }')/vm_core.h)") \
    -include vm_core.h" \
bundle install

i.e.,

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

首先，安装 Ruby 头文件。
```
gem install debugger-ruby_core_source
```

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 头文件。Grepping 的输出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
...

当前的补丁级别是多少？
```
$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]
```
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", ); print }'
2.0.0-p481
```

现在我们运行bundle install，使用ARCHFLAGSset 将包含 ruby 头文件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", ); print }')/vm_core.h)") \
    -include vm_core.h" \
bundle install

IE，

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

For those who's using gem 'pry-debugger'just change it to gem 'pry-byebug'in your Gemfile.

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

Unfortunatelly no answer solved this problem. As answered before by nickh, "Ruby 2.1.2 isn't supported by debugger".

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

I found a japanese post that allowed me to install this gem, but i don't take any responsibility for it, since it's not an official release. Do it at your own risk:

我找到了一个允许我安装这个 gem 的日文帖子，但我对此不承担任何责任，因为它不是官方版本。风险自负：

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