ruby - 无法在系统范围的 rvm 安装上创建 gemset

Question

我正在尝试创建一个 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，根据https://stackoverflow.com/a/5716654/429850的回答, 我做到了

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

如何在多用户 rvm 安装中创建 gemsets？

更新:重启电脑后，将自己加入rvm组，还是不行:

$ 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/系统范围的安装，您需要将需要访问 rvm 的每个用户添加到 rvm 组。
