我是初学程序员,我正在尝试通过命令行运行Rails服务器。我在命令行中键入“rails server”,并收到此错误:
Could not find gem 'sqlite3-ruby (= 1.2.5, runtime)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.
收到此错误后,我运行'bundle install'。一旦我运行'bundle install',我在命令行中键入“rails server”并收到相同的错误:
Could not find gem 'sqlite3-ruby (= 1.2.5, runtime)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.
这是我的GemFile的副本:
source 'http://rubygems.org'
gem 'rails', '3.0.9'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'
# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'
# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
# gem 'webrat'
# end
有人可以帮助我启动并运行我的rails服务器吗?谢谢!

尝试删除gemfile中的“1.2.5”,使其显示为:
gem 'sqlite3-ruby', :require => 'sqlite3'
然后运行
bundle install
再次

我想我很久以前就遇到过这个错误 - 它与我的计算机的ruby目录中的bin或lib文件夹中的sqlite.dll有关。我认为迈克尔哈特尔的教程提到了一些事情。

你试过吗
gem 'sqlite3'

您可能还想确认您的gem已正确安装在您的环境中:
gem list
您还可以获得有关特定宝石的更多信息:
gem specification sqlite3-ruby
我假设您在安装其他gem时没有任何问题 - 也就是说,您不需要为 bundle install 设置http_proxy环境变量。
