Ruby on rails ActiveRecord:：ConnectionAdapters:：列jdbc错误“；“未初始化常量”；在jruby 9和rails 5+；

我正在尝试在Windows 10上安装并运行jruby 9.1.7.0和rails 5.0.1。安装过程中似乎一切正常，但一旦启动服务器，就会立即出现JDBC错误

Java版本

>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Jruby版本

>jruby -v
jruby 9.1.7.0 (2.3.1) 2017-01-11 68056ae Java HotSpot(TM) 64-Bit Server VM 
25.51-b03 on 1.8.0_51-b16 +jit [mswin32-x86_64]

没有安装其他版本的ruby、rails或jruby，当我安装了gem rails时，一切看起来都很好

此时，我进入新创建的目录并测试应用程序，看它是否会启动，但它总是失败，并出现相同的JDBC错误。我尝试过指定mysql并使用默认sqlite，但在这两种情况下，我都得到了以下结果：
