Windows上的Mysql2和Rails

所以。我試圖建立一個Rails應用程序，我試圖在Windows 7這裏這樣做的我做了什麼：Windows上的Mysql2和Rails

使用安裝了Ruby 1.9.3 rubyinstaller
gem update
gem install rails
gem update
rails new
修改了的Gemfile，與mysql2
修改database.yml的正確
bundle install
gem update
新增的對MySQL，是我路上
增加了一個硬連接在紅寶石賓

一切工作的的libmysql C連接到目前爲止，除了當我做rake db:create:all，導致：

rake aborted! 
126: The specified module could not be found. - C:/Ruby193/lib/ruby/gems/1.9.1 
/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/1.9/mysql2.so 
C:/Users/username/Documents/workspace/appname/config/application.rb:7:in `<top (
required)>' 
C:/Users/username/Documents/workspace/appname/Rakefile:5:in `<top (required)>' 
(See full trace by running task with --trace)

wtf？

UPDATE：

完整跟蹤，通過要求：

的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.9' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

gem 'mysql2' 

gem 'json' 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

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

# To use Jbuilder templates for JSON 
# gem 'jbuilder' 

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

# Deploy with Capistrano 
gem 'capistrano'

應用程序，你能後的痕跡？你的gemfile是什麼樣的？ – 2013-01-04 02:58:49

當然，如果你認爲這將有所幫助，謝謝你的期待。 – mschultz

您是否嘗試過指定'gem「mysql2」，「〜> 0.2.7」'然後運行'bundle install' – 2013-01-05 19:02:01

如果我可以推薦。

http://railsinstaller.org/

就是要安裝軌道的最簡單方法。只要確保它匹配正確的系統軟件。

但是，我不認爲這是你的安裝。我認爲這是你改變你的數據庫。首先，我建議使用PG，我認爲它比sql2或sql3好很多。

但是，由於某種原因，你想要sql2，我認爲你修改的database.yml是關閉的。您表示這是正確的，但您可能需要仔細檢查一下。

我不是專家，但也許在這裏有幫助。否則，祝你好運！

我也在MacOS和基於Ubuntu的服務器上運行這個完全相同的rails代碼與git回購），它似乎在這兩種環境中運行得很好。我選擇了使用PostgreSQL上MySQL2 gem的MySQL，因爲它的簡單性和我的經驗 - 對切換到pg不感興趣，而且SQLite不適用於大型數據庫。我也非常喜歡手動導軌安裝（gem install rails），因爲這使得它與其他系統類似。 – mschultz

進出口使用railsinstaller 解決辦法：你要添加的libmysql.dll到Ruby斌，順便說一句，從束installator它的提示，如果你要創建一個擁有--database = mysql的參數

只需將libmysql.dll複製到Ruby bin即可。解決我的問題。 – Domus71
