解决方案

Ubuntu...?

使用它来找出您正在运行的可执行文件:

$ 哪个红宝石/usr/bin/ruby

用它来找出它到底是什么:

$ readlink -f/usr/bin/ruby/usr/bin/ruby1.8

使用它来找出它属于哪个包:

$ dpkg -S/usr/bin/ruby1.8ruby1.8:/usr/bin/ruby1.8

用它来卸载那个:

$ apt-get purge ruby​​1.8

注意:如果您使用版本/环境管理器安装了 Ruby，例如 RVM 或 Rbenv 那么这个方法是行不通的，因为 Ruby 将作为脚本而不是包安装.

解决方案

Ubuntu...?

Use this to find out what executable you're running:

$ which ruby
/usr/bin/ruby

Use this to find out what it actually is:

$ readlink -f /usr/bin/ruby
/usr/bin/ruby1.8

Use this to find out what package it belongs to:

$ dpkg -S /usr/bin/ruby1.8
ruby1.8: /usr/bin/ruby1.8

Use this to uninstall that:

$ apt-get purge ruby1.8

Note: If you have installed Ruby using Version/Environment managers like RVM or Rbenv then this method is not gonna work because Rubies will be installed as scripts not packages.
