Question

我已经从rails 3切换到ruby 2.0.0，rails 4，当我运行命令bundle update rails时，我收到此错误

An error occurred while installing ruby-debug-base19 (0.11.25), and Bundler cannot continue.
Make sure that `gem install ruby-debug-base19 -v '0.11.25'` succeeds before bundling.

但是当运行gem install ruby-debug-base19 -v'0.11.25时，我收到了这个错误：

Answer 1

使用兼容Ruby 2.0的调试器（例如ruby-debug-base19）替换Gemfile中的byebug并再次运行该命令。

ruby 2.0.0和rails 4需要ruby-debug-base19吗？
