刚开始学习Rails。我使用的是Windows Vista,从http://rubyinstaller.org/下载了最新版本的Ruby并成功安装。
ruby -v
ruby 1.9.2p290 (2011-07-09) [i386-mingw32]
我运行:
gem update --system
gem sources -a http://gemcutter.org
gem install rails
没有错误报告。
rails --v
Rails 3.1.0
接下来,我创建了一个文件夹用于存放我的Rails项目,并按照以下步骤创建了新的Rails应用:
rails new test
cd test
bundle install
(再次没有报错)
但是当我运行 rails server
命令时,出现了以下错误:
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,但仍然没有成功...之后,如果我再次输入rails -v,我会得到与之前相同的错误。我必须关闭窗口控制台并重新打开才能使rails -v再次工作!!
有人遇到过这个问题吗?你能帮忙吗?
谢谢!!!
按要求,gemfile内容如下:
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
bundle install 的结果:
