无法在系统范围的rvm安装上创建gemset

Question

我正在尝试创建gemset。首先，我做了

$ rvm gemset create rails-1.3.7 
mkdir: /usr/local/rvm/gems/ruby-1.9.2-p320@rails-1.3.7: Permission denied 
Gemset 'rails-1.3.7' does not exist, 'rvm gemset create rails-1.3.7' first, or append '--create'. 
Can not create environment file for 'rails-1.3.7', Could not use ruby. 
$ sudo rvm gemset create rails-1.3.7 
Password: 
Can not create gemset before using a ruby. Try 'rvm use <some ruby>'. 
$ rvm use 1.9.3 
Using /usr/local/rvm/gems/ruby-1.9.3-p194 
$ sudo rvm gemset create rails-1.3.7 
Can not create gemset before using a ruby. Try 'rvm use <some ruby>'. 
$ sudo rvm use 1.9.3 

RVM is not a function, selecting rubies with 'rvm use ...' will not work. 
You need to change your terminal settings to allow shell login. 
Please visit https://rvm.io/workflow/screen/ for example. 

然后，accoriding答案在https://stackoverflow.com/a/5716654/429850，我做

$ export rvm_gems_path="$HOME/.rvm/gems" 
$ rvm gemset create rails-3.1.7

如何创建在多用户安装RVM gemsets？

更新：后，重新启动计算机，并添加自己的RVM组，我似乎仍不能做到这一点：

$ rvm use 1.9.2 
Gemset '' does not exist, 'rvm gemset create ' first, or append '--create'. 
$ rvm gemset create rails-3.1.7 
'rails-3.1.7' gemset created (/Users/yasir/.rvm/gems/ruby-1.9.3-p194@rails-3.1.7). 
$ rvm use 1.9.2 
Gemset '' does not exist, 'rvm gemset create ' first, or append '--create'. 
$ rvm rails-3.1.7 
Unknown ruby interpreter version: '3.1.7'. 
$ rvm 1.9.2 
Gemset '' does not exist, 'rvm gemset create ' first, or append '--create'. 
$ rvm gemset create 1.9.2 
'1.9.2' gemset created (/Users/yasir/.rvm/gems/ruby-1.9.3-p194@1.9.2). 
$ rvm 1.9.2 
Gemset '' does not exist, 'rvm gemset create ' first, or append '--create'. 
$ rvm use 1.9.2 
Gemset '' does not exist, 'rvm gemset create ' first, or append '--create'.

对于多用户/系统范围内安装，需要将每个需要访问rvm的用户添加到rvm组。
