無法在系統範圍的rvm安裝上創建gemset

Question

我正在嘗試創建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. 

然後，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

如何創建在多用戶安裝RVM gemsets？

更新：後，重新啓動計算機，並添加自己的RVM組，我似乎仍不能做到這一點：

$ 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'.

對於多用戶/系統範圍內安裝，需要將每個需要訪問rvm的用戶添加到rvm組。
