当我执行 rake db:create 显示错误 Constants DL and Fiddle is not Defined 时
我正在使用红宝石2.2.3。我认为我的 rjb 有问题
耙子中止！

我在更新 Java 时偶尔会遇到这个问题，原因似乎是 RJB 人员没有跟上新的 JDK 布局。特别是，RJB 依赖于寻找libjvm.so某个地方$JAVA_HOME/jre，但自 Java 9 发布以来情况并非如此。
我发现的唯一解决方法是创建一个符号链接来复制 Ruby 期望在 Java 主目录中找到的路径。
这在我的 Linux 机器上起作用了（当以 root 身份运行时）：
cd $JAVA_HOME
mkdir -p jre/lib/amd64
ln -s $JAVA_HOME/lib/server/ jre/lib/amd64/server
