在ruby 2.0.0p247上替代'ruby-debug19'（罪魁祸首'linecache19'）？

我很沮丧，因为我已经尝试了其他的StackOverflow文章，但是在修复我自己的错误方面一直没有成功。当我打电话在ruby 2.0.0p247上替代'ruby-debug19'（罪魁祸首'linecache19'）？

'gem install linecache19'

...以下错误outputed

请注意罪魁祸首线...

/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，这并不工作...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：UC Berkeley的软件工程），它尝试安装'linecache19'。

我是否必须降级到ruby1.9，还是可以继续使用ruby2.0？

当我打电话

$ruby -v

我得到以下...

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

我使用RVM。

我有点怀疑linecache19不支持ruby 2.0。

可能是调试器的选择的版本不支持您当前的Ruby版本，更新调试宝石：'捆绑更新debugger'。 – rmagnum2002

尝试对Ruby 2.0安装byebug，而不是调试器。您似乎已经拥有Ruby最低可支持的补丁级别。

2个问题：1）ruby-debug19与调试器相同吗？ 2）如果是这样，将更改为byebug损坏我现有的代码？ – bjliu

1）调试器是ruby-debug19的新端口。 https://github.com/cldwalker/debugger有一个“与ruby-debug19不同的地方”部分。 2）绝对不是，你只需要使用'byebug'，你可以使用'debugger' – HargrimmTheBleak

尝试这样做：

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

不幸的是，我得到了同样的错误... – bjliu

然后尝试使用调试器gem，而不是ruby-debug19，api调用是相同的，我认为调试器更好的支持。我刚才意识到你正在尝试使用ruby-debug19。我从来没有设法让它在1.9+上工作 'gem install debugger - --with-ruby-include = $ rvm_path/src/ruby-2.0.0-p247' – berislavbabic

谢谢！我认为那是罪魁祸首...... 19似乎代表了Ruby1。9，我已经更新了这个问题来反映这个问题 - 现在问题变成了找到ruby-debug19的替代方法，它不适用于Ruby2.0。 – bjliu

在宝石文件

gem 'debugger'

添加这一点，并给

bundle install

调试器和linecache不受红宝石2.0的支持。您可以使用byebug宝石代替。

来指定源代码 – chirag7jain

你只需要更换URL

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

从1.9到2.0
