ruby-on-rails-4 – 如何卸载rvm,ruby,rails和gem.我在小牛身上弄错了

我在Ruby on Rails上是新的,我有一些配置问题.我不知道该怎么办.因为报告问题,我安装了很多次ruby,铁轨和宝石.
我在堆栈溢出中读了很多问题,没有什么可以解决.
我尝试卸载所有东西,当我尝试删除宝石时,我有一些错误：

我在终端上报了一些问题,我不知道如何发送日志等.
这是正确的卸载：

删除宝石：$宝石清洁
-Uninstall ruby​​：$rvm uninstall ruby​​(#this会卸载所有的ruby的安装？)
或需要：
– 按版本卸载：

$rvm uninstall 2.1.0

和其他版本2.0.0和2.1.1

– 卸载rvm：

$rvm repair
$rvm cleanup
$rvm implode

现在再安装一次！

当我尝试我有这个：

解决方法

只需删除rvm文件夹(去除rvm,rubies,gems等)

rm -rf ~/.rvm

要么

rvm implode
