乌班图……？
Use this to find out what executable you're running:
使用它来找出您正在运行的可执行文件：
$ which ruby
/usr/bin/ruby
Use this to find out what it actually is:
使用它来找出它的实际情况：
$ readlink -f /usr/bin/ruby
/usr/bin/ruby1.8
Use this to find out what package it belongs to:
使用它来找出它属于哪个包：
$ dpkg -S /usr/bin/ruby1.8
ruby1.8: /usr/bin/ruby1.8
Use this to uninstall that:
使用它来卸载那个：
$ apt-get purge ruby1.8
Note: If you have installed Ruby using Version/Environment managers like RVMor Rbenvthen this method is not gonna work because Rubies will be installed as scripts not packages.
注意：如果您已经使用RVM或Rbenv等版本/环境管理器安装了 Ruby，那么此方法将不起作用，因为Ruby将作为脚本而不是包安装。

If you used rbenvto install it, you can use
如果你曾经rbenv安装过它，你可以使用
rbenv versions
to see which versions you have installed.
查看您安装了哪些版本。
Then, use the uninstall command:
然后，使用卸载命令：
rbenv uninstall [-f|--force] <version>
for example:
例如：
rbenv uninstall 2.4.0 # Uninstall Ruby 2.4.0

If you have installed Ruby using RVM then the following command will completely remove RVM installed directory:
如果您已经使用 RVM 安装了 Ruby，那么以下命令将完全删除 RVM 安装目录：
rvm implode
rvm implode
Running this command will ask for your confirmation to delete the .rvmdirectory.
运行此命令将要求您确认删除.rvm目录。
After it completes deleting the .rvmdirectory, you get the following message which is worth notable:
完成删除.rvm目录后，您会收到以下值得注意的消息：
Note you may need to manually remove /etc/rvmrc and ~/.rvmrc if they exist still.
Please check all .bashrc .bash_profile .profile and .zshrc for RVM source lines and delete or comment out if this was a Per-User installation.
请注意，如果 /etc/rvmrc 和 ~/.rvmrc 仍然存在，您可能需要手动删除它们。
请检查所有 .bashrc .bash_profile .profile 和 .zshrc 以获取 RVM 源代码行，如果这是每用户安装，请删除或注释掉。
