Answer 1

我解决this..i只需走进Gemfile中，改变了mysql2提及MySQL和东西工作得很好...

Answer 2

您提供的输出中的最后一行清楚地表明您错过了什么。它提到没有安装gem mysql2，并且您应该运行bundle install来安装它们。

你没有提到你如何获得该版本的Ruby，但我会假设你安装了Rubyinstaller包。

现在，mysql2 gem目前缺少Windows的二进制文件（这是我正在处理的东西）。

我有两个建议：无论您使用的sqlite3（它应该制定出与RubyInstaller盒子或专门RailsInstaller包

或者你下到RubyInstaller wiki发布有关安装的那些类似的说明进行安装和编译mysql2宝石。和编译MySQL适配器。

希望这一切都有助于或有意义。
