答
通过以下方式安装:
$ gem install pry
$ pry
然后添加:
require 'pry'; binding.pry
进入您的程序。
从撬
0.12.2开始,没有导航命令,例如 next
, break
等。其他一些宝石也提供了此功能,例如,参见 pry-byedebug
。
As of pry
0.12.2 however, there are no navigation commands such as next
, break
, etc. Some other gems additionally provide this, see for example pry-byedebug
.
