ruby-on-rails – 启动Rails服务器的问题

ruby -v
ruby 1.9.2p290 (2011-07-09) [i386-mingw32]

我跑：

gem update --system
gem sources -a http://gemcutter.org
gem install rails

没有错误报告.

rails --v
Rails 3.1.0

在此之后,我为我的Rails项目创建了一个文件夹,我在里面创建了一个新的Rails应用程序,如下所示：

rails new test
cd test
bundle install

(再次没有报错)

但是,当我运行rails服务器时,我收到此错误：

rails server
←[31mCould not find rails-3.1.0 in any of the sources←[
←[33mRun `bundle install` to install missing gems.←[0m

我尝试再次运行bundle但没有再次成功…在此之后,如果我再次键入rails -v我会得到与以前相同的错误.我必须关闭Windows控制台并重新打开rails -v才能重新开始工作！

有没有人经历过这个？！你能帮我吗？

谢谢！！！

根据要求,gemfile内容为：

source 'http://rubygems.org'

gem 'rails','3.1.0'

# Bundle edge Rails instead:
# gem 'rails',:git => 'git://github.com/rails/rails.git'

gem 'sqlite3'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',"  ~> 3.1.0"
  gem 'coffee-rails',"~> 3.1.0"
  gem 'uglifier'
end

gem 'jquery-rails'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19',:require => 'ruby-debug'

group :test do
  # Pretty printed test output
  gem 'turn',:require => false
end
