Question

我正在尝试让我的Rails应用程序使用MySQL而不是默认的SQLite。我创建了一个新项目，强制使用似乎正常工作的MySQL。

它在Gem文件中添加了gem条目，如下所示：

source 'https://rubygems.org'

    gem 'rails', '3.2.13'

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

    gem 'mysql2'

当我运行bundle命令时，它显示它使用mysql gem：

Using mysql2 <0.3.11>

我还将database.yml文件配置为：

development:
 adapter: mysql2
 encoding: utf8
 reconnect: false
 database: dbname
 pool: 5
 username: uname
 password: pass
 host: hostname

test:
 development:
 adapter: mysql2
 encoding: utf8
 reconnect: false
 database: dbname
 pool: 5
 username: uname
 password: pass
 host: hostname

production:
 development:
 adapter: mysql2
 encoding: utf8
 reconnect: false
 database: dbname
 pool: 5
 username: uname
 password: pass
 host: hostname

但是当我尝试运行rails服务器时，我得到了这个：

C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/l ib / mysql2 / mysql2.rb：2：require': 126: The specified module could not be found . - C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-min gw32/lib/mysql2/1.9/mysql2.so (LoadError) from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11- x86-mingw32/lib/mysql2/mysql2.rb:2:in' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11- x86-mingw32 / lib / mysql2.rb:9:in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11- x86-mingw32/lib/mysql2.rb:9:in' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib / bundler / runtime.rb：72：在require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:72:in块中（2级）in require' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib / bundler / runtime.rb：70：在each' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:70:in块中的require' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib / bundler / runtime.rb：59：in each' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:59:in require' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib / bundler.rb：132：require' from C:/Users/n00151956/Desktop/RubyProjects/Demo/config/application.rb: 7:in' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3 / lib / rails / commands.rb：53：在require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:53:in块中' 来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3 / lib / rails / commands.rb:50:in tap' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:50:in' 来自script / rails：6：require' from script/rails:6:in'

我能够使用默认的SQLite运行rails服务器但是在我的生活中我无法使用MySQL。如果有人能帮我解决这个问题会有很大的帮助！

Answer 1

从 - mysql-connector下载libmysql.dll文件并将其放入C：\ RailsInstaller \ Ruby1.9.3 \ bin应该在Image
以管理员身份打开命令提示符并以下列方式启动mysql服务器：C：\ Program Files \ MySQL \ MySQL Server 5.0 \ bin \ mysql

development:
  adapter: mysql2
  database: proj_development
  username: root
  password: pass
  host: 127.0.0.1
  socket: /tmp/mysql.sock

test:
  adapter: mysql2
  database: proj_test
  username: root
  password: pass
  host: 127.0.0.1
  socket: /tmp/mysql.sock

production:
  adapter: mysql2
  database: proj_production
  username: root
  password: pass
  host: 127.0.0.1
  socket: /tmp/mysql.sock

Answer 2

Install Mysql如果您没有安装它。

下载MySQL-connector（zip文件） - 下载noinstall版本（不适用于安装）。您应该将其提取到c:\mysql-connector-c-your-version-download
将libmysql.dll从c:\mysql-connector-c-your-version-download复制到C:\RailsInstaller\Ruby1.9.3\bin
安装MySQL gem

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-your-version-download

无法使Rails服务器与MySQL一起使用
