耙子中止！无法加载这样的文件 - mysql/mysql_api

我正在使用Fedora19。耙子中止！无法加载这样的文件 - mysql/mysql_api

[[email protected] coffee]# ruby -v 
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux] 
[[email protected] coffee]# rails -v 
Rails 3.0.

这是我的Gemfile

source 'http://rubygems.org' 

gem 'rails', '3.0.9' 

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


gem 'mysql' 

# 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-ruby', :require => '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

当我做耙分贝：迁移，我得到这个错误

[[email protected] coffee]# rake db:migrate 
rake aborted! 
cannot load such file -- mysql/mysql_api 
/home/charul/coffee/config/application.rb:7:in `<top (required)>' 
/home/charul/coffee/Rakefile:4:in `<top (required)>' 
(See full trace by running task with --trace)

MySQL是安装在我的系统。

[[email protected] coffee]# service mysqld restart 
Redirecting to /bin/systemctl restart mysqld.service

这是我的database.yml文件。

development: 
    adapter: mysql 
    encoding: utf8 
    database: ajax 
    username: root 
    password: root123 
    host: 127.0.0.1 
    port: 3306

另外，bundle install命令可以很好地工作。

[[email protected] coffee]# bundle install

试试'宝石'mysql2''和米ysql安装在你的系统中..？ – Nithin

不，它没有奏效。仍然有相同的错误 – Charul

你的yml文件是什么样子？ –

env ARCHFLAGS="-arch x86_64" gem install mysql --version '2.8.1' -- --with-mysql- config=/usr/local/Cellar/mysql/5.5.15/bin/mysql_config

而应该用mysql宝石mysql2。只要做到：

gem install mysql2

改变你的数据库适配器在您的database.yml文件

development: 
    adapter: mysql

到

development: 
    adapter: mysql2

，改变你的Gemfile：

#gem 'mysql' 
gem 'mysql2'
