所以。我正在尝试开发一个 Rails 应用程序，并且我正在尝试在 Windows 7 中这样做。这是我所做的：

  1. 使用 ruby​​installer 安装 Ruby 1.9.3
  2. gem update
  3. gem install rails
  4. gem update
  5. rails new
  6. 修改了gemfile，替换sqlite3为mysql2
  7. 正确修改 database.yml
  8. bundle install
  9. gem update
  10. 将mysql添加到我的路径
  11. 在 ruby​​ bin 中添加了到 libmysql c 连接器的硬链接

到目前为止一切正常，除了当我这样做时rake db:create:all，这会导致：

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)

什么？

更新：

完整跟踪，应要求：

我正在使用 railsinstaller 解决方案：如果您使用 --database=mysql 参数创建应用程序，则必须将 libmysql.dll 添加到 Ruby bin，顺便说一句，它来自 bundle installator 的提示

如果我可以推荐。

http://railsinstaller.org/

是安装导轨的最简单方法。只要确保它匹配正确的系统软件。

但是，我认为这不是您的安装。我认为这是您更改了数据库。首先，我推荐使用 PG，我认为它比 sql2 或 sql3 好很多。

但是，鉴于您出于某种原因需要 sql2，我认为您修改后的 database.yml 已关闭。您说它是正确的，但您可能需要仔细检查它。

我不是专家，但也许这里有一些帮助。否则，祝你好运！
