我已经在 Linux Mint v14 Nadia 上安装了 rails 4.0.0.rc1。
当我跑
rails new something
它给了我错误（我将只放最后几行）：
创建 vendor/assets/stylesheets/.keep 运行 bundle install /var/lib/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/ui.rb:36:in
initialize': undefined method[]' for # (NoMethodError)来自 /usr/lib/ruby/vendor_ruby/bundler/cli.rb:12:innew' from /usr/lib/ruby/vendor_ruby/bundler/cli.rb:12:ininitialize' 来自 /usr/lib/ruby/vendor_ruby/bundler/vendor/thor.rb:263:innew' from /usr/lib/ruby/vendor_ruby/bundler/vendor/thor.rb:263:indispatch' 来自 /usr/lib/ ruby/vendor_ruby/bundler/vendor/thor/base.rb:386:instart' from /var/lib/gems/1.9.1/gems/bundler-1.3.5/bin/bundle:20:inblock in '来自/var/lib/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/friendly_errors.rb:3:在with_friendly_errors' from /var/lib/gems/1.9.1/gems/bundler-1.3.5/bin/bundle:20:in'
然后我更改目录以检查依赖项：
cd something
bundle check
它说：
解决依赖关系... Bundler 无法满足您的 Gemfile 的依赖关系。使用
bundle install.
然后我运行：
捆绑安装
它显示：

我认为这里发生了一些奇怪的事情。也许我的安装不正确...
