我只红宝石2.0安装

rvm list 

rvm rubies 

=* ruby-2.0.0-p0 [ x86_64 ] 

# => - current 
# =* - current && default 
# * - default

我该如何解决这个问题？

2.0其实是非常新的。也许试试'rvm install 1.9.3'和'rvm use 1.9.3'然后再试试'rails new app_name'？ – 2013-03-23 14:00:18

2.0已发布！ – 2013-03-23 14:12:52

你的$ PATH是什么？什么是'哪个轨道'和'哪个宝石'的输出？在'gem list'的输出中是否包含Rails？ – 2013-03-23 14:46:03

好像你没有安装railties信息：

gem install railties
