无法安装rails（LoadError）

Question

我正在尝试安装rails并完成

gem install rails

返回：

Fetching: rails-4.0.0.gem (100%)
Successfully installed rails-4.0.0
Installing ri documentation for rails-4.0.0
1 gem installed
Successfully installed rails-4.0.0

然后我输入rails -v

然后返回

/usr/local/rvm/rubies/ruby-1.9.3-p448/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- /Users/ericfilkins/config/boot (LoadError)
from /usr/local/rvm/rubies/ruby-1.9.3-p448/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require'
from script/rails:5:in `<main>'

有人能引导我朝正确的方向前进吗？
