Question

我在安装Ruby方面犯了一些错误，现在我尝试卸载它（How to remove ruby from ubuntu），但它发出以下错误。我尝试使用sudo apt-get purge ruby，但仍然无法卸载。它显示未安装ruby，但我检查并确认它已安装在/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]

Answer 1

如果你想完全删除红宝石，

sudo apt-get purge ruby rubygems

或者您可以按照以下步骤操作，

使用它来查明它是什么

$ 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

Answer 2

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

Answer 3

我已从ruby目录中删除了home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

最后它被卸载了!! 感谢Rick
