Ruby on rails Rake中止（精简解析器.so）

我正在使用Bitnami Redmine安装。我尝试通过一些插件扩展Redmine，但RAKE命令失败

C:\Bitnami\redmine-2.4.3-0\apps\redmine\htdocs>rake
rake aborted!
126: The specified module could not be found.   - C:/Bitnami/redmine-2.4.3-0/apps/redmine/htdocs/vendor/bundle/ruby/2.0.0/gems/thin-1.3.1-x86-mingw32/lib/thin_parser.so

原因：

根本原因是版本依赖性不正确（我使用Ruby 2.0.0、Windows 7 32位（也在64位版本上检查）

如果您使用的是BITNAMI REDMINE设置，则可能存在内部不一致性

解决方案： 安装最新的mysql2驱动程序和精简版，然后在redmine目录中编辑gem文件以使用这些最新版本。对我来说，目前是：

[...]
    gem 'thin', '1.6.2'
[...]
    when 'mysql2'
    gem "mysql2", "0.3.15", :platforms => [:mri, :mingw]
[...]

[...]
    gem 'thin', '1.6.2'
[...]
    when 'mysql2'
    gem "mysql2", "0.3.15", :platforms => [:mri, :mingw]
[...]
