Ruby gem安装无法正常工作 – GEM_PATH

问题

当运行rvm ruby??gems最新时我收到此错误：

Error running 'env GEM_PATH=/Users/sjc/.rvm/gems/ruby-2.0.0-p0:/Users/
sjc/.rvm/gems/ruby-2.0.0-p0@global:/Users/sjc/.rvm/gems/ruby-2.0.0-p0:

s/ruby-2.0.0-p0 /Users/sjc/.rvm/rubies/ruby-2.0.0-p0/bin/ruby /Users/s
jc/.rvm/src/rubygems-2.0.0/setup.rb',please read /Users/sjc/.rvm/log/
ruby-2.0.0-p0/rubygems.install.log

日志(rubygems.install.log)有这个：

RubyGems 2.0.0 installed

因为我不知道自己在做什么,所以我认为我早先尝试安装sass可能会导致这种情况.我遵循了these instructions,因此在当天早些时候执行这些命令.

$export GEM_HOME=/home/mygemrepository
$ruby setup.rb --prefix=/home/mystuff

同样,如果GEM_HOME和GEM_PATH看起来正确那么重要.

$echo $GEM_HOME
/Users/sjc/.rvm/gems/ruby-2.0.0-p0
$echo $GEM_PATH
/Users/sjc/.rvm/gems/ruby-2.0.0-p0:/Users/sjc/.rvm/gems/ruby-2.0.0-p0@global

有什么我可以/应该做的成功安装rubygems？任何帮助表示赞赏.
