在ruby 2.0.0p247上替代'ruby-debug19'（罪魁祸首'linecache19'）？ [英] Alternative to 'ruby-debug19' (culprit 'linecache19') on ruby 2.0.0p247?

问题描述

我很沮丧，因为我在这个问题上尝试了其他的StackOverflow文章，但在解决我自己的错误方面一直没有成功。当我打电话时

 'gem install linecache19'
  

...出现以下错误

 错误：安装linecache19错误：
错误：无法构建gem原生扩展。

显然这不起作用... url  http://ftp.ruby-lang.org/pub/ ruby / 1.9 / ruby​​-2.0.0-p247.tar.gz 没有任何意义。 （访问Ruby1.9然后查找Ruby2.0 tar.gz）
 
 
这是一个类项目（对于CS169：加州大学伯克利分校的软件工程）需要gem'ruby-debug19'，它会尝试安装'linecache19'。
 
 
 
 是否必须降级到ruby1.9，还是可以继续使用ruby2。 0

我有点怀疑linecache19不支持ruby 2.0。
解决方案
尝试安装 byebug ，而不是Ruby 2.0调试器。您似乎已经拥有了Ruby的最低可支持补丁级别。
 
I am frustrated because I have tried other StackOverflow articles on this issue, but have been unsuccessful in fixing my own error. When I call
'gem install linecache19'

/home/user/.rvm/gems/ruby-2.0.0-p247/gems/ruby_core_source-0.1.5/lib/contrib/uri_ext.rb:268:in `block (2 levels) in read': Looking for http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-2.0.0-p247.tar.gz and all I got was a 404! (URI::NotFoundError)
Obviously this does not work...the url http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-2.0.0-p247.tar.gz doesn't make sense. (Accesses Ruby1.9 then looks for the Ruby2.0 tar.gz)

This is for a class project (for CS169: Software Engineering at UC Berkeley) that requires the gem 'ruby-debug19', which tries to install 'linecache19'.

Do I have to downgrade to ruby1.9, or can I keep using ruby2.0?

When I call
$ruby -v
I get the following...
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
I am using RVM.

I am slightly suspicious that linecache19 does not support ruby 2.0.
解决方案
Try installing byebug instead of debugger for Ruby 2.0. You already seem to have the minimum supportable patchlevel of Ruby.
