Ubuntu 如何从系统中完全删除rbenv、rvm、ruby和rails？

我想从我的系统中完全删除rbenv、rvm、Ruby和Rails，这样我就可以从头开始安装rbenv和Ruby了。我尝试对rbenv和rvm使用

sudo-apt-remove

，

sudo-apt-purge

，

sudo-apt-autoremove

，以及

sudo-apt-uninstall

，并且删除了

~/.rvm

和

~/.rbenv

文件夹，但这两个文件夹似乎仍然安装在我的机器上。每次尝试后，我都会重新启动终端。我希望版本管理器、所有gems和所有Ruby版本都能从系统中完全清除，不留下任何痕迹。这样做的正确方式是什么

更新： 我通过重复以前尝试过的所有步骤成功地删除了rbenv，但是，现在在尝试删除rvm时，出现以下错误：

dpkg: rvm: dependency problems, but removing anyway as you requested:
 ruby-full depends on ruby; however:
  Package ruby is not configured yet.
  Package rvm which provides ruby is to be removed.
 rake depends on ruby | ruby-interpreter; however:
  Package ruby is not configured yet.

我在这里找到了一个答案，解决了这个问题：

如果有人想将此标记为副本或其他东西。

你说他们似乎安装在我的机器上是什么意思？

apt list--installed | grep rvm

返回

rvm/now 1.29.3-1 all[installed，local]

和

$rbenv--version

返回

rbenv 1.1.1.1-37-g1c772d5
