Question

我很沮丧，因为我在这个问题上尝试了其他StackOverflow文章，但是在修复我自己的错误方面却没有成功。当我打电话

'gem install linecache19'

...以下错误已经过时

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'，它试图安装'linecache19'。

我是否必须降级为ruby1.9，还是可以继续使用ruby2.0？

当我打电话

$ruby -v

我得到以下内容......

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

我正在使用RVM。

我有点怀疑linecache19不支持ruby 2.0。

Answer 1

尝试为Ruby 2.0安装byebug而不是调试器。您似乎已经拥有Ruby的最低可支持补丁级别。

Answer 2

Ruby 2.0不支持

调试器和linecache。你可以改用byebug gem。

Answer 3

尝试这样做：

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

Answer 4

在宝石文件中添加

   gem 'debugger'

并给予

   bundle install

Answer 5

你只需要替换url中的代码

/家庭/ {您的用户名] /。RVM /宝石/红宝石2.0.0-P645 /宝石/ ruby_core_source-0.1.5 / LIB / ruby_core_source.rb

从1.9到2.0

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