这可能是一个新手设置问题。 但是这里…
机器设置
我有一个Windows 7 64位机运行轨4.0.0和ruby2.0.0我有以下在我的path
C:\Ruby200-x64\bin;C:\RubyDevKit\bin;C:\RubyDevKit\mingw\bin; 项目设置
我正在从一个同事的工作仓库克隆git项目。
当我运行我的初始
rake db:migrate
我得到以下错误
rake aborted! Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 's qlite3'` to your Gemfile. C:/Working/mynewproject/config/environment.rb:5:in `<top (required)>' Tasks: TOP => db:migrate => environment (See full trace by running task with --trace)
我的Gemfile包含gem'sqlite3'，如下所示
# Use sqlite3 as the database for Active Record gem 'sqlite3'
完整的Gemfile是
source 'https://rubygems.org' ruby '2.0.0' # Bundle edge Rails instead: gem 'rails', github: 'rails/rails' gem 'rails', '4.0.0' gem 'rails_12factor', group: :production # Use sqlite3 as the database for Active Record gem 'sqlite3' # Use SCSS for stylesheets gem 'sass-rails', '~> 4.0.0' # Use Twitter Bootstrap for styling gem 'bootstrap-sass' # Use Uglifier as compressor for JavaScript assets gem 'uglifier', '>= 1.3.0' # Use CoffeeScript for .js.coffee assets and views gem 'coffee-rails', '~> 4.0.0' # See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem 'therubyracer', platforms: :ruby # Use jquery as the JavaScript library gem 'jquery-rails' # Turbolinks makes following links in your web application faster.

当我运行bundle install我得到以下列表 – 注意sqlite3的缺席

当我做bundle show 'sqlite3'我得到
Could not find gem 'sqlite3'. Did you mean sqlite3?
当我做gem install 'sqlite3'我得到
Successfully installed sqlite3-1.3.8-x64-mingw32 Parsing documentation for sqlite3-1.3.8-x64-mingw32 unable to convert "\x90" from ASCII-8BIT to UTF-8 for lib/sqlite3/2.0/sqlite3_native.so, skipping 1 gem installed
经过查找有关“无法转换”的错误，我发现我可以安装没有文档。 所以，如果我这样做
gem install 'sqlite3' --no-doc
我明白了
Successfully installed sqlite3-1.3.8-x64-mingw32 1 gem installed
然后当我这样做
rake db:migrate
我仍然得到
rake aborted! Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 's qlite3'` to your Gemfile. C:/Working/mynewproject/config/environment.rb:5:in `<top (required)>' Tasks: TOP => db:migrate => environment (See full trace by running task with --trace)
那么，我错过了什么？
谢谢
在评论中提出build议之后更新：
由于Doon的评论，我把gemfile的内容放在了上面问题的描述中
为了回应techvineet的评论，我已经用一致的输出来执行bundle install几次了。
由于zrl3dx的评论，我现在已经运行了bundle exec bundle并获得相同的输出，即

由于Sachin Singh的评论，我删除了Gemfile.lock并运行bundle install 。 结果几乎相同：

所以仍然没有提到sqlite3和rake db:migrate仍然结果

为了回应Sachin Singh的问题， ruby -v command的输出是什么？
它说：
ruby 2.0.0p247 (2013-06-27) [x64-mingw32]
和rails – 版本说
Rails 4.0.0
Prusswan问，在同一台机器上还有其他的ruby安装吗？
有三个 – 1.9.2，1.9.3和2.0.0后者是path中的一个。 另外两个我已经删除。
Bundler和x64-mingw32 Ruby有一个已知的问题，它没有检测到x64-mingw32 gem平台，因此导致失败。
我相信这已经在1.4.0预发布版本中得到了修复，您可以通过下面的方法来尝试：
gem update bundler --pre bundle install
还有其他的问题，你可能会遇到的64位版本。 以下是我个人的建议：
除非你真的被迫使用超过2GB内存的应用程序（很可能不是Rails应用程序），否则我建议你使用Ruby的32位版本（以及相应的DevKit）
虽然你有一个64位版本的Windows，但是系统却能够正常运行32位应用程序。 使用Rails开发Web应用程序时，性能不会下降。
尽管Ruby 2.0.0已经被标记为稳定且可以生产，但是并不是所有的宝石和相关工具都已经更新，可以正常使用。 还有一些粗糙的方面需要解决，比如Bundler和64位Ruby。 作为大多数开源软件，这是一个社区的努力，可能需要帮助。
希望这可以帮助。
