RVM 能用 Gem 来安装？ 关于 RVM 看 WIKI http://ruby-china.org/wiki/rvm-guide

问题是我的确用 gem 安装成功了…… $ gem list *** LOCAL GEMS ***

…… rvm (1.9.2) ……

从 rubygems.org 中搜索了一下，还真有这个 gem. 没从 gem 安装过。 都是按 rvm 的官方网站的方法安装的。

安装完 rvm gem 时的提示：

This gem contains only the Ruby libraries for the RVM Ruby API.

In order to install RVM please use one of the methods listed in the documentation:

https://rvm.beginrescueend.com/rvm/install/

such as,

bash < <(curl -s -B https://rvm.beginrescueend.com/install/rvm)

followed by placing the sourcing line in your ~/.bash_profile or wherever may be appropriate for your setup (example, .zshenv, /etc/profile, ...):

# Load RVM into a shell session as a function [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

After completing setup please open a new shell to use RVM and be sure to run 'rvm notes' to gain a list of dependencies to install before installing the first Ruby. You can read more details about this process on the above mentioned install page as well as the basics page:

Enjoy!

我也没有从 gem 安装过，你找一下 rvm 的命令在什么地方，然后把路径加入到 PATH 里就可以了，比如我的在~/.rvm/bin 下，你看看在没有，还是在 ruby 的 gem 目录下 说实话，rvm 是用来管理 ruby 和 gems 的，所以还是用命令来装比较好
