我很沮丧，因为我已经尝试过有关此问题的其他 StackOverflow 文章，但未能成功修复我自己的错误。当我打电话

'gem install linecache19'

...输出以下错误

ERROR:  Error installing linecache19:

请注意罪魁祸首...

/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)

显然这不起作用......网址http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-2.0.0-p247.tar.gz没有意义。（访问 Ruby1.9 然后查找 Ruby2.0 tar.gz）

这是一个需要 gem 'ruby-debug19' 的类项目（用于 CS169：加州大学伯克利分校的软件工程），它试图安装 'linecache19'。

我必须降级到 ruby​​1.9，还是可以继续使用 ruby​​2.0？

当我打电话

$ruby -v

我得到以下...

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

我正在使用 RVM。

I am slightly suspicious that linecache19 does not support ruby 2.0.

Try installing byebug instead of debugger for Ruby 2.0. You already seem to have the minimum supportable patchlevel of Ruby.

debugger and linecache are not supported by Ruby 2.0. You can use byebug gem instead.

Try doing this:

gem install linecache19 -- --with-ruby-include=$rvm_path/src/ruby-2.0.0-p247

Add this in your gem file 

   gem 'debugger'

and give 

   bundle install

you just need to replace the code in url

/home/{your-user-name]/.rvm/gems/ruby-2.0.0-p645/gems/ruby_core_source-0.1.5/lib/ruby_core_source.rb

from 1.9 to 2.0
