仍然在我的 rvm 环境中与一个有害的错误作斗争：

    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

这看起来像是一个路径问题，因为它在 Debian 附带的默认 Ruby 中查找。这是我的路径：

/home/caseyr/.rvm/gems/ruby-2.0.0-p0/bin:/home/caseyr/.rvm/gems/ruby-2.0.0-p0@global/bin:/home/caseyr/.rvm/ rubies/ruby-2.0.0-p0/bin:/home/caseyr/.rvm/bin:/home/caseyr/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11 :/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 Rails 有自己的独立路径吗？不知道，但这是有启发性的：

which rails
/usr/bin/rails

这似乎完全忽略了 rvm，因为路径应该指向 ruby​​ 2.0.0。怎么会这样？

gem 环境似乎还可以：

    $ gem env

我意识到已经回答了类似的问题（例如this one），但仍然没有找到让我了解真正发生的事情的问题（经过多次删除、重新安装等......）

任何帮助都感激不尽; 真的很想让 Rails 再次工作......

首先查看使用 rvm 安装了哪些 rubies

rvm list

它将显示已安装的 ruby​​ 版本。

然后利用rvm --default use ruby-2.0.0-p0

然后使用创建gemsetrvm gemset create gemset1

rvm use ruby-2.0.0-p0@gemset1

gem install rails -v rails_version

安装后尝试rails -v
