从UBUNTU 14.0.4 LTS卸载Ruby时出现错误

Question

我在安装Ruby时犯了一些错误，现在我正试图卸载它(如何从ubuntu中删除Ruby)，但它给出了以下错误。我尝试了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位置/usr/local/bin/ruby。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]

Answer 1

如果您正在使用rvm，那么您可以使用命令

卸载ruby 1.8.7

rvm unistall 1.8.7

，然后使用命令

卸载RVM

rvm implode

Answer 2

如果你想完全删除ruby，

sudo apt-get purge ruby rubygems

或者你可以按照下面的步骤，

用这个找出它是什么

$ readlink -f /usr/local/bin/ruby
/usr/local/bin/ruby1.8.7

使用此命令查找正在使用的包:

$ dpkg -S /usr/local/bin/ruby1.8.7
ruby1.8: /usr/local/bin/ruby1.8.7

并使用这个来安装，

$ apt-get purge ruby1.8.7

Answer 3

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

终于被卸载了!!感谢Rick
