Ruby on Rails安装问题-如何使用WAMP MySQL安装?

问题描述

我执行了以下操作，以在Windows XP上安装Ruby on Rails:

I did the following to install Ruby on Rails on Windows XP:

• 已安装 ruby​​installer-1.9.2-p0.exe
• 宝石安装导轨
• gem安装mysql2
• cd my_dir
• 发布新的my_app -d mysql

• Installed rubyinstaller-1.9.2-p0.exe
• gem install rails
• gem install mysql2
• cd my_dir
• rails new my_app -d mysql

创建的 config/database.yml 包含以下MySQL配置:

The created config/database.yml contains the following MySQL configuration:

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: first_development
  pool: 5
  username: root
  password:
  host: localhost

但是，当我从 my_dir 运行 rails服务器时，出现以下错误:

However, when I run rails server from my_dir I got the following error:

D:/Programs/Ruby192/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6-x86-mingw32/lib/mysql2
/mysql2.rb:2:in `require': 126: The specified module could not be found.   - D:/
Programs/Ruby192/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6-x86-mingw32/lib/mysql2/1.
9/mysql2.so (LoadError)
...

以及以下弹出消息:

The application has failed to start because LIBMYSQL.dll was not found. Re-installing the application may fix this problem.

我想问题是MySQL的安装.

The problem, I guess, is the installation of MySQL.

我已经安装了WAMP，我想使用它的MySQL安装.

I have WAMP installed, and I would like to use its MySQL installation.

我搜索了 libmysql.dll ，并确实在以下位置找到了它:my_path_to_wamp\bin\mysql\mysql5.1.36\bin\libmysql.dll

I searched for libmysql.dll and indeed found it in: my_path_to_wamp\bin\mysql\mysql5.1.36\bin\libmysql.dll

问题是我如何告诉Rails进行此MySQL安装?

The question is how would I tell Rails to take this installation of MySQL ?

推荐答案

以前安装mysql gem时遇到了这个问题，一个快速的解决方法是将libmysql.dll复制到您的ruby bin文件夹中.最近，我在WAMP MySQL服务器上运行了Rails，没有任何问题，因此，如果不能解决问题，请在解决依赖性问题后发布更具体的错误消息，然后查看配置.

I've had this problem when installing the mysql gem before, and a quick fix is just to copy the libmysql.dll into your ruby bin folder. I recently got rails running off of a WAMP MySQL server without a problem, so if this doesn't solve it post a more specific error message once you've sorted out the dependency issue and I'll look at my configuration.

具体来说，我正在运行XAMPP.

Just to be specific, I'm running XAMPP.
