Rails宝石问题

Question

我刚刚使用Ruby 1.9.3p0安装了Rails 3.2.1

davesahil@sahil-pc:~$ gem list rails

*** LOCAL GEMS ***

rails (3.2.1)

$rails --version 给了我这个

/home/davesahil/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems.rb:314:in `bin_path': can't find gem rails ([">= 0"]) with executable rails (Gem::GemNotFoundException)
    from /home/davesahil/.rvm/gems/ruby-1.9.3-p0/bin/rails:19:in `<main>'

自从我上次在铁轨上工作以来已经有一段时间了.我在这里错过了一些东西吗？

Answer 1

我对rails 3.2.1和ruby 1.8.7也有同样的问题.以下对我有用:

sudo gem install railties
