从 UBUNTU 14.0.4 LTS 卸载 Ruby 时出错
error in uninstalling Ruby from UBUNTU 14.0.4 LTS
我在安装 Ruby 时犯了一些错误，现在我正在尝试卸载它 (How to remove ruby from ubuntu)，但出现以下错误。我尝试使用 sudo apt-get purge ruby 但仍然无法卸载。它显示 ruby 没有安装，但我确实检查并确认它安装在 /usr/local/bin/ruby 位置。请帮我从我的机器上卸载 Ruby 和 RVM。
$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]
$ sudo apt-get purge ruby 1.8.7

如果您想完全删除 ruby，
sudo apt-get purge ruby rubygems
或者您可以按照以下步骤操作，
使用它来找出它是什么
$ readlink -f /usr/local/bin/ruby
/usr/local/bin/ruby1.8.7
使用它来找出正在使用的包：
$ dpkg -S /usr/local/bin/ruby1.8.7
ruby1.8: /usr/local/bin/ruby1.8.7
并使用它来安装，
$ apt-get purge ruby1.8.7
如果您使用的是 rvm，则可以使用命令
卸载 ruby 1.8.7
rvm unistall 1.8.7
然后使用命令
卸载 rvm
rvm implode
我已经从 home 目录中删除了 ruby 目录并按照以下步骤操作...
$ whereis ruby
ruby: /usr/local/bin/ruby /usr/local/lib/ruby
$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]
$ sudo rm -rf /usr/local/bin/ruby
$ sudo rm -rf /usr/local/lib/ruby
$ ruby -v
bash: /usr/local/bin/ruby: No such file or directory
终于卸载了！！
感谢Rick
