没有 Ruby 无法在 macOS 中安装 RVM，没有 RVM 无法升级 Ruby

Question

我当前的 Ruby 版本是：

$ ruby -v 
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]

我需要更新版本的 Ruby 所以我尝试安装它，但是我没有安装 RVM:

$ rvm
-bash: rvm: command not found

为了安装 RVM，我去了 https://rvm.io 并按照说明进行操作。但是，在第二个命令中，我得到了以下信息：

$ \curl -sSL https://get.rvm.io | bash -s stable

Can not save config data for ruby: 'ruby-2.5.1', most likely it is broken installation and you can:
- try fix it: 'rvm reinstall ruby-2.5.1', OR:
- remove  it: 'rvm uninstall ruby-2.5.1 --gems'
Upgrade of RVM in /Users/me/.rvm/ is complete.

但是，RVM 没有安装或升级，因为我仍然得到：

$ rvm reload
-bash: rvm: command not found

有人知道问题出在哪里吗？我知道我可以在没有 RVM 的情况下升级 Ruby，但我不想这样做。

Answer 1

答案是输入：

$ source ~/.rvm/scripts/rvm

然后升级ruby

rvm reinstall ruby-2.5.1

所以我现在有

$ ruby -v
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin16]

没有 Ruby 无法在 macOS 中安装 RVM，没有 RVM 无法升级 Ruby

Cannot install RVM in macOS without Ruby, cannot upgrade Ruby without RVM
