无法在rails项目上获取我的ruby来创建数据库

Question

这可能是一个新手设置问题.但是这里......

机器设置

我有一台运行rails 4.0.0和ruby 2.0.0的Windows 7 64位机器我的路径中有以下内容

C:\Ruby200-x64\bin;C:\RubyDevKit\bin;C:\RubyDevKit\mingw\bin;

项目设置

我正在从同事的工作存储库中的克隆git项目开始工作.

当我运行我的初始

rake db:migrate

我收到以下错误

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确实包含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. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

# Use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

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

# Use Capistrano for deployment
# gem 'capistrano', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]

gem 'protected_attributes' # should probably use strong parameters!

当我运行时,bundle install我得到以下列表 - 请注意缺少sqlite3

我什么时候bundle show 'sqlite3'得到

Could not find gem 'sqlite3'.
Did you mean sqlite3?

我什么时候gem install 'sqlite3'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

在搜索了"无法转换"错误之后,我发现我可以在没有文档的情况下安装.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

我还是得到的

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)>'

(See full trace by running task with --trace)

那么,我错过了什么？

谢谢

在评论中建议的事情后更新:

作为Doon评论的结果,我已将gemfile内容放在上述问题的描述中

为了回应techvineet的评论,我已经bundle install多次运行并保持一致的输出.

由于zrl3dx的评论,我现在已经运行bundle exec bundle并得到相同的输出,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:

Use `bundle show [gemname]` to see where a bundled gem is installed.

所以仍然没有提到sqlite3 rake db:migrate仍然导致

rake aborted!
Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 's
qlite3'` to your Gemfile.

在回答Sachin Singh的问题时,输出是ruby -v command什么？

它说:

ruby 2.0.0p247 (2013-06-27) [x64-mingw32]

和rails - 版本说

Rails 4.0.0

普鲁斯万问在同一台机器上还有其他红宝石装置吗？

有三个 - 1.9.2,1.9.3和2.0.0后者是路径中的一个.我已经删除了另外两个.

Answer 1

Bundler和64bits Ruby存在一个已知问题,即没有将x64-mingw32gem平台检测到bundle中,从而使其失败.

我相信这已在1.4.0预发布版本中得到修复,您可以通过执行以下操作来尝试:

gem update bundler --pre

bundle install

64位版本可能会遇到其他问题.以下是我个人对此的建议:

除非您真的被迫工作或创建使用超过2GB RAM的应用程序(很可能不是Rails应用程序),否则我建议您使用32位版本的Ruby(和相应的DevKit)

虽然你有一个64位版本的Windows,但该系统能够毫无问题地运行32位应用程序.使用Rails开发Web应用程序时,没有明显的性能下降.

虽然Ruby 2.0.0已被标记为稳定且生产就绪,但并非所有gem和相关工具都已更新,无法正常使用它.还有一些需要解决的粗糙边缘,正如您在Bundler和64位Ruby的情况下所看到的那样.作为大多数开源软件,这是一项社区工作,可能需要帮助.

希望这可以帮助.
