【问题描述】：
我正在尝试创建一个 gemset。首先，我做到了
$ 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 gemset？
更新：重启电脑，加入rvm组后，好像还是不行：
$ 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'.
【问题讨论】：
-
不要将 sudo 与非 sudo rvm 混合使用。最好不要使用 sudo。
-
@Thilo，我只在 sudo 说权限被拒绝时才使用它。我该如何解决这个问题？
-
它不应该拒绝任何权限，除非你不小心以root身份安装了一些东西。如果您必须使用 sudo，请查看 stackoverflow.com/questions/3644897/…，但我建议您在您的用户帐户下全新安装 rvm。
-
哦，我明白了，这是系统范围的安装。不建议这样做，因为它可能会导致这些问题。见rvm.io/rvm/install。
