我已经四处搜索，但我无法找到有效的答案。

我对此完全陌生，所以当你回答时，请像我是一个孩子一样解释......或者像我是一块西兰花一样解释。如果你想让我安装一些东西，告诉我要写什么。

好吧，我正在尝试遵循这个http://guides.fatfreecrm.com/Setup-Microsoft-Windows.html并且我已经到了我应该写的地方， rake db:create RAILS_ENV=production 我得到的只是这个：（我已经完成了“gem install mysql2”，我已经按照教程安装了 rake，没有发现任何问题）

C:\RailsInstaller\fat_free_crm>rake db:create RAILS_ENV=production --trace

我有同样的问题并在花了两个小时后修复了它。也许它也会帮助你。所以这里是引导我解决问题的步骤

  1. 我假设您正在运行 32 位 mysql，因为 64 位 + 32 位 mysql 的问题可能是其他问题
  2. 确保 mysql.dll 与已安装的 gem 兼容（我有 mysql2）
  3. 为避免问题从http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip/from/pick下载
  4. 将 mysql.dll 复制到您的 ruby​​/bin

总结：对我来说是rails mysql2 gem和我机器上安装的那个不兼容的问题
