ruby-on-rails – 无法在rails项目上获取我的ruby以创建数据库

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-x64bin;C:RubyDevKitbin;C:RubyDevKitmingwbin;

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bundle install时,我得到以下列表 – 请注意缺少sqlite3

当我做捆绑show’sqlite3’时,我得到了

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

当我做gem安装’sqlite3’时,我得到了

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)>'
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)

那么,我错过了什么？

谢谢

在评论中建议的事情后更新：

由于Doon的评论,我已将gemfile内容放在上述问题的描述中

为了回应techvineet的评论,我已经多次使用一致的输出运行bundle install.

由于zrl3dx的评论,我现在运行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并运行了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和rake db：migrate仍会导致

rake aborted!
Specified 'sqlite3' for database adapter,but the gem is not loaded. Add `gem 's
qlite3'` to your Gemfile.
C:/Working/its-a-disaster/config/environment.rb:5:in `<top (required)>'

针对Sachin Singh的问题,ruby -v命令的输出是什么？

它说：

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

和rails – 版本说

Rails 4.0.0

Prusswan问同一台机器上还有其他ruby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.

gem update bundler --pre

bundle install
