为什么不是rvm安装的Rails版本的工作？

仍然在我的RVM环境有害的错误挣扎：为什么不是rvm安装的Rails版本的工作？

rails -v 
/usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:296:in `to_specs': Could not find 'railties' (>= 0) among 0 total gem(s) (Gem::LoadError) 
    from /usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:307:in `to_spec' 
    from /usr/local/lib/site_ruby/1.8/rubygems/core_ext/kernel_gem.rb:47:in `gem' 
    from /usr/bin/rails:22

这看起来像一个路径问题，因为它正在寻找在默认的Ruby自带的Debian的。这是我的路径：

/home/caseyr/.rvm/gems/ruby-2.0.0-p0/bin:/home/caseyr/.rvm/gems/[email protected]/bin ：/home/caseyr/.rvm/rubies/ruby-2.0.0-p0/bin：/home/caseyr/.rvm/bin：/家庭/ caseyr /斌：在/ usr/local/bin目录：在/ usr/bin中： /斌：在/ usr/bin中/ X11：在/ usr /游戏

然而，这是默认的Ruby版本：

ruby -v 
ruby 2.0.0p0 (2013-02-24 revision 39474) [i686-linux]

难道是Rails有它自己的，独立的路径？不知道，但这是有益的：

which rails 
/usr/bin/rails

这似乎完全忽略rvm，因为路径应该指向ruby 2.0.0。怎么会这样？

宝石环境似乎确定：

我知道有这样类似的问题已经回答（如this one），但仍然没有找到一个已经让我明白了什么是真正回事（经过几次移除，重新安装等...）

任何帮助将不胜感激;真的很想让Rails的工作了......

第一次看到它的红宝石使用RVM

rvm list

它会显示已安装的Ruby版本安装。

然后利用rvm --default use ruby-2.0.0-p0

然后使用rvm gemset create gemset1

rvm use [email protected] 

gem install rails -v rails_version

安装尝试后rails -v
