blocks|key|517904|text|其他人在评论中试图窥探，我就是这么做的。这是Rails所必需的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|517905|#+Gemfile

Someone else posted in a comment to try Pry, which is what I did. This is what's necessary for Rails:

<pre><code># Gemfile
gem 'pry-rails'


# In your Rails Project where you want a 'debugger'

puts 'i want to insert some code between this'

binding.pry

puts 'and this'
</code></pre>

Immediately after installing I notice my <code>.irbrc</code> doesn't load, so I don't get pretty console output. I also added this to my '~/.pryrc'

<pre><code># setting up pry to have irb helpers like reload!
if defined?(Rails) &amp;&amp; Rails.env
 extend Rails::ConsoleMethods
end
</code></pre>

Pry has some nice features that I've wanted to check out, and I may yet return to ruby-debug once there's a simple way to integrate it into a Rails project for Ruby 1.9.3. I can run the curl command from the other answers, but this is something I'll have to point my teammates to for our Rails project, so it doesn't scale well IMO.

blocks|key|517970|text|也许不是这个问题的最终答案，但我是由一系列封闭的副本引导到这里的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|517971|对我来说，问题是我同时在Ruby1.8和Ruby1.9中运行一个项目，而我的Gemfile需要这样的更改：|517972|gem+'debugger',+:require+=>+'ruby-debug',+:platforms+=>+:mri_19

Maybe not the definitive answer to this question, but I was lead here by a chain of closed duplicates.

For me the problem was that I run a project in both ruby 1.8 and ruby 1.9, and my Gemfile needed this change:

<pre><code>gem 'debugger', :require =&gt; 'ruby-debug', :platforms =&gt; :mri_19
gem 'ruby-debug', :platforms =&gt; :mri_18
</code></pre>

Now it works for both rubies.

I just updated to Ruby 1.9.3p0 and Rails 3.1.1. Now when I try to launch the server, it complains that I should install <code>ruby-debug</code>, even though it's already installed.

<pre><code>% rails server --environment=development --debug
=&gt; Booting WEBrick
=&gt; Rails 3.1.0 application starting in development on http://0.0.0.0:3000
=&gt; Call with -d to detach
=&gt; Ctrl-C to shutdown server
You need to install ruby-debug to run the server in debugging mode. With gems, use 'gem install ruby-debug'
Exiting
</code></pre>

In my Gemfile I have

<pre><code># see: http://stackoverflow.com/questions/1083451/debugging-in-ruby-1-9
gem 'ruby-debug-base19', "0.11.24"
gem 'ruby-debug19', "0.11.6"

Is it possible to run debug with the latest version of Ruby?

ruby-debug with Ruby 1.9.3?
